Question

Circumference of the base of cylinder is $6m$ and height is $44m$. Find its volume.

Answer 1

Circumference of base of cylinder $=6m\left(\text{Given}\right)$

$2\pi r=6$

$\Rightarrow r=\frac{3}{\pi }{cm}^2$

Also,

Height of cylinder $=44cm\left(\text{Given}\right)$

As we know that,

Volume of cylinder $=\pi r^{2}h$

Therefore,

Volume of cylinder $=\pi \times {\left(\frac{3}{\pi }\right)}^2\times 44=\frac{3\times 3\times 7}{22}\times 44=126m^3$
