Two solids are described in the list below.
One solid is a sphere and has a radius of 3 inches
The other solid is a cylinder with a radius of 3 inches and a height of 3 inches.
What is the difference between the volumes, in cubic inches, of the solids in terms of
?

A.9
B.18
C.27
D.36

Answer 1

27

Explanation:

volume of sphere

• V=4 /3πr³= 4/3*3.14*3³= 113.04 in³

volume of cylinder

• V=πr²h= 3.14*3³= 84.78 in³

difference in volumes

• 113.04 - 84.78= 28.26 in³

closest option is 27
