Question

Find the volume of a right circular cylinder whose radius is $10.5\text{cm}$ and height is $16\text{cm}$.

Answer 1

We know that the volume of a right circular cylinder with radius $r$ and height $h$ is $V=\pi r^{2}h$.

It is given that the height is $h=16\text{cm}$ and the radius is $r=10.5\text{cm}$, therefore,

$\begin{array}{cc}V& =\frac{22}{7}\times (10.5{)}^2\times 16\\ & =\frac{22}{7}\times 110.25\times 16\\ & =5544{\text{cm}}^3\end{array}$

Hence, the volume of cylinder is $5544{\text{cm}}^3$.
