(C) $1$. The internal diameter of the hemispherical tank is $14\, m$,so the radius $r = 7\, m$.$2$. The volume of a hemispherical tank is given by $V = \frac{2}{3} \pi r^3$.$3$. $V = \frac{2}{3} 	imes \frac{22}{7} 	imes 7 	imes 7 	imes 7 = \frac{2}{3} 	imes 22 	imes 49 = \frac{2156}{3} = 718 \frac{2}{3}\, m^3$.$4$. We know that $1\, m^3 = 1\, kilolitre$. Therefore,the tank contains $50\, m^3$ of water.$5$. The volume of water to be pumped = (Total capacity) - (Volume already present).$6$. Volume to be pumped = $718 \frac{2}{3} - 50 = 668 \frac{2}{3}\, m^3$.

The water for a factory is stored in a hemispherical tank whose internal diameter is $14\, m$. The tank contains $50\, kilolitres$ of water. Water is pumped into the tank to fill it to its capacity. Calculate the volume of water pumped into the tank (in $m^3$).
