Question

The radius of a sphere is 3 inches. Which represents the volume of the sphere?
12 cubic inches
36 cubic inches
64 cubic inches
81 cubic inches

Answer 1

Answer:
The volume is 37.7 inches cubed

Step by Step:

Volume of a sphere is: 4/3 pi radius squared

The radius of 3 squared is 9

4/3 of 9 is 12

and 12 times pi is 37.6991118431
(I rounded to nearest tenth which is 37.7)
