Question

Find the volume of right circular cone (in $c{m}^3$) with radius $6cm$ and height $7cm$.

Answer 1

Given that, $r=6cm,$ $h=7cm$

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

$V=\frac{1}{3}\times \frac{22}{7}\times {\left(6cm\right)}^2\times 7cm$ $(\pi =\frac{22}{7})$

$V=\frac{1}{3}\times 22\times 36{cm}^3$

$V=22\times 12{cm}^3$

$V=264{cm}^3$
