Since the surface area of this cylinder is \(432\pi \;yd^2\), its diameter is equal to 12 yards.
How to calculate surface area.Mathematically, the surface area (SA) of a cylinder is given by this formula:
\(S.A = 2\pi rh + 2\pi r^2\)
Where:
h is the height.r is the radius.Given the following data:
Surface area of cylinder = \(432\pi \;yd^2\)Height = 5r.Substituting the given parameters into the formula, we have;
\(432\pi = 2\pi r(5r) + 2\pi r^2\\\\432\pi = 2\pi 5r^2 + 2\pi r^2\\\\216=5r^2+r^2\\\\216=6r^2\\\\r^2=36\\\\r=\sqrt{36}\)
r = 6 yards.
For the diameter:
Diamter = 2 x radius
Diamter = 2 x 6
Diameter = 12 yards.

Answer:
1. The formula for finding the surface area of a cylinder is:
Surface Area = 2πr(r + h)
Where:
* `r` is the radius of the cylinder
* `h` is the height of the cylinder
The surface area of a cylinder is the total area of all the surfaces that make up the cylinder. This includes the two circular bases and the lateral surface. The lateral surface is the curved surface that wraps around the cylinder.
To find the surface area of a cylinder, we first need to find the area of each of the circular bases. The area of a circle is πr², where `r` is the radius of the circle. So, the area of each of the circular bases of a cylinder is πr².
We then need to find the area of the lateral surface. The lateral surface is a rectangle with height `h` and width equal to the circumference of the base. The circumference of a circle is 2πr. So, the width of the lateral surface is 2πr.
The area of a rectangle is length x width. So, the area of the lateral surface of a cylinder is 2πrh.
Adding the areas of the two circular bases and the lateral surface, we get the total surface area of the cylinder:
Surface Area = 2πr(r + h)
2. The formula for finding the surface area of a sphere is:
Surface Area = 4πr²
Where:
* `r` is the radius of the sphere
The surface area of a sphere is the total area of all the surfaces that make up the sphere. This includes the entire curved surface of the sphere.
To find the surface area of a sphere, we simply need to square the radius of the sphere and multiply it by π.
For example, if the radius of a sphere is 5 cm, the surface area of the sphere would be:
Surface Area = 4π(5 cm)² = 523.6 cm²

Answer:
Max made a mistake in step 5.
He should have used division instead of multiplication.
Step-by-step explanation:
In step #5, he made the mistake of multiply 5/6 by 5/6. The reason why this doesn't work is because y is not a full y. When there isn't a number beside a variable, it is implied that it is 1y. To solve for y, you need 1y or else results or inaccurate.
In reality, 5/6 * 5/6 is equal to 25/36. If you divided 5/6 by 5/6, it is equal to 1, which makes y a full y.

Edo and kofi shared an amount of 21,000. 00 in the ratio 2:5respectively how much more did kofi recieve than Esi
Kofi received 9,000 more amount than Edo.
given that
Edo and kofi shared an amount of 21,000. 00 in the ratio 2:5respectively
To find out how much more Kofi received than Edo, we need to first find out how much each person received based on the given ratio.
Let's call the amount of money that Edo received "E" and the amount that Kofi received "K".
The ratio of the amounts that they received is given as 2:5, which means that we can represent the amounts as:
E:K = 2:5
We can rewrite this as:
E/K = 2/5
We know that the total amount of money they received is 21,000, so we can also write:
E + K = 21,000
Now we can use these two equations to solve for E and K:
E/K = 2/5
E + K = 21,000
First, let's solve the first equation for E in terms of K:
E/K = 2/5
E = (2/5)K
Now we can substitute this expression for E into the second equation and solve for K:
E + K = 21,000
(2/5)K + K = 21,000
(7/5)K = 21,000
K = (5/7) * 21,000
K = 15,000
So Kofi received 15,000.
Now we can find out how much more Kofi received than Edo by subtracting Edo's amount from Kofi's amount:
K - E = 15,000 - (2/5) * 15,000
K - E = 15,000 - 6,000
K - E = 9,000
Therefore, Kofi received 9,000 more than Edo.

a rectangular rug has an area of 160 square feet the lengut of the rug is 6 feet longer than the width
The width of the rug is 10 feet, and the length is 16 feet.
Let's assume the width of the rectangular rug is "x" feet.
According to the given information, the length of the rug is 6 feet longer than the width, so the length would be "x + 6" feet.
The formula for the area of a rectangle is length multiplied by width.
We can set up an equation using this formula to solve for the width:
Area = Length × Width
160 = (x + 6) × x
Now, let's simplify the equation:
\(160 = x^2 + 6x\)
Rearranging the equation:
\(x^2 + 6x - 160 = 0\)
Now we have a quadratic equation.
We can solve it by factoring, completing the square, or using the quadratic formula.
In this case, let's solve it by factoring:
(x + 16)(x - 10) = 0
Setting each factor to zero:
x + 16 = 0 or x - 10 = 0
Solving for x:
x = -16 or x = 10
Since we are dealing with measurements, we can disregard the negative value.
Therefore, the width of the rug is 10 feet.
Now, we can find the length by adding 6 to the width:
Length = x + 6 = 10 + 6 = 16 feet.

a histogram with the hills to the far left means the image is overexposed.
The statement "A histogram with the hills to the far left means the image is overexposed" is not accurate. In fact, a histogram with the hills to the far left indicates that the image is underexposed, not overexposed.
A histogram is a graphical representation of the distribution of pixel values in an image. It displays the frequency of occurrence of different tonal values. The horizontal axis represents the tonal values, while the vertical axis represents the frequency or number of pixels.
When the hills of the histogram are concentrated towards the left side, it means that a significant portion of the image has darker or lower tonal values. This indicates an underexposed image, where the exposure settings were insufficient to capture enough light, resulting in a darker overall appearance.
Conversely, an overexposed image would have the hills of the histogram concentrated towards the right side, indicating that a significant portion of the image has brighter or higher tonal values.
Therefore, the correct interpretation is that a histogram with the hills to the far left means the image is underexposed, not overexposed.

for n.
we would need a sample size of at least 502 for the approximate probability of the random interval (Y1/n - Y2/n) ‡ 0.05 covering pi - p2 to be at least 0.80.
To compute n, we can use the formula:
n = ((zα/2)^2 * 2p*(1-p*)) / (ε^2)
Where zα/2 is the z-score associated with a confidence level of 1-α, p* is the probability of success for a binomial distribution, and ε is the margin of error.
Since we are given that the approximate probability of the random interval (Y1/n - Y2/n) ‡ 0.05 covering pi - p2 is at least 0.80, we can set α = 0.20 to find the corresponding z-score of 1.28.
Using p* = 1/2 as an upper bound for both P1 and P2, we can calculate the margin of error as:
ε = zα/2 * sqrt((p*(1-p*)) / n)
Plugging in the values, we get:
0.05 = 1.28 * sqrt((0.25) / n)
Solving for n, we get:
n = 501.76
Therefore, we would need a sample size of at least 502 for the approximate probability of the random interval (Y1/n - Y2/n) ‡ 0.05 covering pi - p2 to be at least 0.80.

The inequality given by (x/3) + 5 ≥ 1/6 has the solution x ≥ -29/2 or [-29/2 , +∞).
Inequality refers to the relationship between two non-equal expressions. It can be denoted by > for greater than, < for less than, >/= for greater than and equal to, and </= for less than and equal to.
To solve an inequality is to find the values of x such that when we substitute that number for x we have a true statement.
Given the inequality (x/3) + 5 ≥ 1/6, subtract 5 from both sides.

the length of a rectangular piece of sheet metal is longer than its width. a square piece that measures on each side is cut from each corner, then the sides are turned up to make a box with volume . find the length and width of the original piece of sheet metal.
The width of the original piece of sheet metal is (w^2 - l^2)/(3w + 3l), and the length is (l^2 - w^2)/(3w + 3l).
To solve this problem, we can use the formula for the volume of a rectangular box, which is V = lwh, where l is the length, w is the width, and h is the height.
First, let's find the height of the box. Since we cut squares from each corner, the height of the box is the length of the square that was cut out. Let's call this length x.
The width of the box is the original width minus the lengths of the two squares that were cut out, which is w - 2x.
Similarly, the length of the box is the original length minus the lengths of the two squares that were cut out, which is l - 2x.
Now we can write the volume of the box in terms of x, w, and l:
V = (w - 2x)(l - 2x)(x)
Expanding this expression, we get:
V = x(4wl - 4wx - 4lx + 8x^2)
Simplifying further:
V = 4x^3 - 4wx^2 - 4lx^2 + 4wlx
To find the dimensions of the original piece of sheet metal, we need to maximize this volume. We can do this by taking the derivative of the volume with respect to x and setting it equal to zero:
dV/dx = 12x^2 - 8wx - 8lx + 4wl = 0
Solving for x, we get:
x = (2wl)/(3w + 3l)
Now we can use this value of x to find the width and length of the original piece of sheet metal:
w - 2x = w - 2(2wl)/(3w + 3l) = (w^2 - l^2)/(3w + 3l)
l - 2x = l - 2(2wl)/(3w + 3l) = (l^2 - w^2)/(3w + 3l)
