Question

Find the volume of a hemisphere whose radius is $\frac{3}{2}cm$.

Answer 1

Given that, the radius of a hemisphere is $\frac{3}{2}cm$.

To find out: The volume of the hemisphere.

We know that, volume of a hemisphere is $\frac{2}{3}\pi r^3$

$\therefore$ Volume of the given hemisphere $=\frac{2}{3}\times \frac{22}{7}\times {\left(\frac{3}{2}\right)}^3[\because \pi =\frac{22}{7}]$

$\Rightarrow \frac{1188}{168}=7.07c{m}^3$

Hence, the volume of the given hemisphere is $7.07c{m}^3$.
