Question

The volume of a right circular cone of height $8cm$ and radius of base $3cm$ is

• A. $12\pi c{m}^3$
• B. $24\pi c{m}^3$
• C. $48\pi c{m}^3$
• D. $72\pi c{m}^3$

Answer 1

The correct option is B $24\pi c{m}^3$

Given that height of right circular cone $h=8cm$

Radius of right circular cone $r=3cm$

Volume of right circular cone$V=\frac{1}{3}{r}^2\pi .h$

$=\frac{1}{3}{.3}^{2.}\pi .8c{m}^3$

$=24\pi c{m}^3$

Hence, this is the answer.
