Find the volume of a cone whose radius is 2 cm and height is 7cm

Concept: Volume of right circular cone is given by:

$\Rightarrow V=\frac{1}{3}\pi r^{2}h$

Given: r = 2 cm and h = 7 cm

Therefore,

$\Rightarrow V=\frac{1}{3}\pi {\left(2\right)}^2.7$

$\Rightarrow \frac{1}{3}\times \frac{22}{7}.4.7=\frac{88}{3}$

$\Rightarrow 29.3$

Hence, the volume of cone is $29.3 c{m}^3$.
