Question

Find the capacity (in litres) of a cylindrical storage tank of height $1.2m$ and base diameter $35cm$.

Answer 1

Height of the tank $=1.2m$

Radius of the base $=\frac{35}{2}=17.5cm=0.175m$

Capacity of the tank $=$ Volume of the tank

As we know that volume of the cylinder is given as-

$V=\pi r^{2}h$

$\therefore$ Capacity of the tank $=\frac{22}{7}\times {\left(0.175\right)}^2\times 1.2=0.1155m^3=0.1155\times 1000(\because 1m^3=1L)=115.5L$
