Question

Find the volume of a right circular cone with radius $5$ cm and height $7$ cm.

Answer 1

We know that the volume of a right circular cone with radius $r$ and height $h$ is $V=\frac{1}{3}\pi r^{2}h$.

It is given that the height of the cone is $h=7$ cm and radius $r=5$ cm, therefore,

$V=\frac{1}{3}\pi r^{2}h=\frac{1}{3}\times \frac{22}{7}\times (5{)}^2\times 7=\frac{22\times 25}{3}=183.33$ cm${}^3$

Hence, the volume of the cone is $183.33$ cm${}^3$.
