Question

What is the volume of a cylinder with a height of 7 in. and a radius of 2 in.? Provide the exact answer.

Answer 1

To find the volume of a cylinder, start with the formula for the volume of a cylinder.

Volume =
`\pi r^(2) h`

Answer 2

84.78 cubic inches

Explanation:

The volume of a cylinder is found using the volume formula
`V=\pi r^2h`.

Substitute h=7 and r = 2.

`V = \pi r^2h\\V = \pi (2^2)(7)\\V=\pi *4*7\\V = 27\pi \\V= 84.78`
