Question

A sphere has a radius of 31 millimeters. Find it's volume to the nearest tenth please. (Use 3.14 for pi)

Answer 1

V ≈ 124,725 mm^3

Explanation:

Let's use the formula for volume of a sphere:

`v = (4)/(3)\pi {r}^(3)`

`v = (4)/(3) (3.14) {31}^(3)`

`v = (4)/(3)(3.14)29791`

`v = (4)/(3) 93543.74`

`v = (4)/(3) * (93543.74)/(1) = (374174.96)/(3)`

`v = 374174.96 / 3`
