Question

The volume of clay used to build a cylindrical pillar with a height of 9 centimeters is 324 pi cubic centimeters. The area of the base of the pillar is ____ pi square centimeters

Answer 1

Answer:

36 (Fill 3 in the blank)

Step-by-step explanation:

Given:

Volume of a cylinder = 324 π

Height = 9 cm

The formula to find the volume of a cylinder = Base area * height.

Base is a circle. So the area of a circle = πr^2

Volume of the cylindrical pillar = πr^2 h

324 π = πr^2 . 9

πr^2 = 324 π /9

πr^2 = 36 π

The area of the base = 36 π
