Question #6d9c2

Answer 1

`v = 36 pi r^3` or `v = 113.097 r^3`

Explanation:

The volume of a sphere is computed using this formula

`v = 4/3 pi r^3`

such that:
`v` = volume
`r` = radius of the sphere

In this case, since you have a sphere with `radius = 3r` then you would need to substitute the given radius of the sphere to the value of `r` in the formula.

`v = 4/3 pi r^3`
`v = 4/3 pi (3r)^3`
`v = 4/3 pi (27r^3)`
`v = 36 pi r^3`
`v = 113.097 r^3`
