Question

The volume of a sphere with a 10-in. radius is

A.)400 pi in^3
B.)1,333 1/3 pi in^3
C.)4,000 pi in^3

Answer 1

V = 4/3 * (pi) * r^3
V = 4/3 * (pi) * 10^3
V = 4/3 * (pi) * 1000
V = 4000/3(pi)
V = 1333 1/3 (pi) in^3 <==

Answer 2

volume of a sphere = 4/3 * PI *r^3

v = 4/3*PI *10^3

v = 4/3*PI*1000

v = 1333 1/3PI in^3

Answer is B
