Question

Find the volume of a cone if the radius of its base 1.5 cm and its perpendicular height is 5 cm.

Answer 1

Given that, the radius of the base of a cone is $1.5cm$ and its height is $5cm$.

To find out: The volume of the cone.

We know that, volume of a cone $=\frac{1}{3}\times \pi r^{2}h$

$\therefore$ Volume of the given cone $=\frac{1}{3}\times \frac{22}{7}\times {1.5}^2\times 5[\because \pi =\frac{22}{7}]$

$\Rightarrow \frac{1}{3}\times \frac{22}{7}\times 2.25\times 5=\frac{247.5}{21}$

$\therefore$ Volume of the cone $=11.79c{m}^3$.

Hence, the volume of the given cone is $11.79c{m}^3$.
