Question

What is the approximate volume of the cone with the height of 12 in. and radius of 9 in.??

Use 3.14 for pi

​

Answer 1

1,017.36 cubic inches

Explanation:

The volume of the cone is found using the volume formula for a cone
`V=(1)/(3)\pi r^2h`.

Substitute h=12 and r = 9.

`V = (1)/(3)\pi r^2h\\V = (1)/(3)\pi (9^2)(12)\\V=(1)/(3)\pi *81*12\\V = (972)/(3)\pi \\V= 324\pi =1,017.36`
