Answer 2

Answer:

$36\pi cm^2$

Step-by-step explanation:

We are given that

Volume of cylinder =$324\pi cm^3$

Height of cylinder=9 cm

We have to find the area of  base of the pillar.

We know that

Volume of cylindrical pillar=$Base\times Height$

Where Base=$\pi r^2$

Substitute the values then we get

$324\pi =Base\times 9$

$Base=\frac{324\pi}{9}=36\pi cm^2$

Hence, the area of base of the pillar=$36\pi cm^2$
