Question

Express the following as a rule for each geometrical figure.

The volume of a cylinder $\left(V\right)$ is equal to$\pi$ times the square of the radius $\left(r\right)$ times the height $\left(h\right)$ of the cylinder .

Answer 1

We know that, volume of cylinder $=\pi \times {(radius)}^2\times height$

If we denote,

The radius of cylinder by $r$

The height of cylinder by $h$

Then,

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

Hence , volume of cylinder is $\pi r^{2}h$.
