Question

What is the volume of a sphere with a radius of 4 m rounded to the nearest square meter?

Answer 1

268m^3

Explanation:

v= 4/3*3.14*r^3

v= 4/3*3.14*4^3= 268m^3

Answer 2

recall -- the volume of a sphere with a radius r ,

`V= (4)/(3) * \pi *r^3`

use the radius here as r = 4 m, calculate the volume

`V= (4)/(3) * \pi * 4^3 = ...`
