Question

The circumference of the base of a cylindrical vessel is $132$ cm and its height is $25$ cm. Find the volume of cylinder. (use $\pi =\frac{22}{7}$).

Answer 1

Volume of a Cylinder = Area of base x Height of cylinder.

Circumference of base = 132 cm.

Let radius of base = $r$

$\Rightarrow 2\pi r=132\Rightarrow r=\frac{7\times 132}{44}=21cm$

Area of the base = $\pi r^2=1386c{m}^2$

Therefore, volume of the cylinder is $\pi r^{2}h=1386\times 25=34650c{m}^3$
