Question

what is the volume of a sphere with radius
r is given by the formula v=4/3 r^3

Find the volume of sphere with radius 4 meters. use 3.14 for the value of x and
round your answer to the nearest tenth.

Answer 1

4/3*4^3
85.3

Answer 2

your formula is incorrect , it should say

V = (4/3)π r^3

so if r = 4
V = (4/3)π(4^3)
= 256π/3 = appr. 267.9 m^3
