Question

The height of a cylinder is $6cm$ and base area is $5c{m}^2$. What is the volume of the cylinder ?

Answer 1

Base area $=5{cm}^2\left(\text{Given}\right)$

$\pi r^2=5$

$\Rightarrow r^2=\frac{5}{\pi }{cm}^2$

Also,

Height of cylinder $=6cm\left(\text{Given}\right)$

As we know that,

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

Therefore,

Volume of cylinder $=\pi \times \frac{5}{\pi }\times 6=5\times 6=30{cm}^3$
