Question

Find the volume of a cone that has a radius of 9 and a height of 13.

Answer 1

Answer is provided in the image attached.

Answer 2

`351 \pi` (about 1102.69902)

Explanation:

The volume of a cone is represented by the formula
`V=\pi r^2 (h)/(3)`, where
`V` is the volume,
`r` is the radius, and
`h` is the height.

1. Substitute in the values.
   `V=\pi * 9^2 * (13)/(3)`
2. Simplify the exponent.
   `V=\pi * 81 * (13)/(3)`
3. Multiply.
   `V=351 \pi`

This is as simple as the solution can get without estimating, but we can estimate with a calculator.
`351 \pi` is approximately equal to 1102.69902.
