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

Answers

Answer:

V ≈ 124,725 mm^3

Step-by-step 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
