What is the volume of a cylinder, in cubic feet, with a height of 20 feet and a base diameter of 8 feet? Round to the nearest tenths place

Answer 1

To find the volume of a cylinder, you use the formula V = πr^2h, where r is the radius of the base of the cylinder and h is the height.

First, you need to find the radius from the diameter given. The radius is half the diameter, so the radius is 8/2 = 4 feet.

Next, plug in the values into the formula:
V = π(4)^2(20)
V = π(16)(20)
V = 320π cubic feet

Now, you can calculate the volume:
V ≈ 320 * 3.14159
V ≈ 1005.31 cubic feet

So, the volume of the cylinder is approximately 1005.3 cubic feet.
