Question
A hemispherical tank has the inner radius of 2.8m. Find its capacity in liters.
✓

Answer

Radius of the tank = 2.8m Therefore Capacity $=\frac{2}{3\pi\text{r}^3}$$=\frac{2}{3}\times\frac{22}{7}\times(2.8)^3=45.994\text{m}^2$
$1\text{m}^3=1000\mid$
Therefore capacity in litres = 45994 litres
