Question

What is the volume of a sphere, to the nearest cubic inch, if the radius equals 5 inches? Use π = 3.14.

Answer 1

`523.6 {in}^(3)`

Explanation:

`v = (4)/(3) \pi {r}^(3) \\ = (4)/(3) \pi * 5 * 5 * 5 \\ = 523.6 {in}^(3)`

Answer 2

V = 523 in^3

Explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

V = 4/3 ( 3.14) * 5^3

V = 523.33333repeating

Rounding to the nearest inch^3

V = 523 in^3
