Question

A hemispherical tank has inner radius of 2.8 m. Find its capacity in litres.

Answer 1

Radius of hemispherical tank (r) = 2.8 m

$\therefore Volumeofthetank=\frac{2}{3}\pi r^3=\frac{2}{3}\times \frac{22}{7}\times 2.8\times 2.8\times 2.8m^3=45.99m^3$
Capacity of water $45.99\times 1000$ litres
$=45990$ litres
