Question

If the radius of the hemisphere is 21 cm, then find its volume?

Answer 1

Hi mate !!

Radius of the hemisphere is ( r ) = 21cm

Volume of Hemisphere =
$= \frac{2}{3} \pi \: {r}^{3}$


$= \frac{2}{3} \times 3.14 \times 21 \times 21 \times 21$

$= \frac{2}{3} \times 3.14 \times 9261$


$= 2 \times 3.14 \times 3087$
$= 19386.36 {cm}^{3}$
