Question

If the volume of a spherical ball is 113.04 cubic inches, what is the radius?

3 inches
9 inches
18 inches
27 inches

Answer 1

r= 3 inches

Step-by-step explanation:

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

113.04= (4/3)*3.14*r^3

113.04*(3/4)= 3.14*r^3

84.78 = 3.14*r^3

84.78/3.14 = r^3

27 = r^3 Take the cubed root of both sides.

r = 3 inches
