Question

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

Answer 1

@kashblood are you familiar with the formula for the volume of a cylinder?

Answer 2

The Volume (V) of a Cylinder of Hight (h) and Radius (r) is given by,
\[V=\pi*r^2h.\]
We are given that, \[V=324\pi, h=9.\]
Hence, the Area of the (circular) Base of the pillar is,
\[\pi*r^2=V/h=324\pi/9=36\pi cm^2.\]
