Calculate the volume of a given cylinder having a height of 20 cm and a base radius of 14 cm.

Given the height of the cylinder = 20 cm  and the radius of the cylinder = 14 cm

The volume of the cylinder = ${\mathrm{\pi r}}^2\mathrm{h}$

           $$\begin{gathered} = \frac{22}{7}\times 14\times 14\times 20 \\ = 12320 {\mathrm{cm}}^3 \end{gathered}$$

Therefore the volume of the given cylinder is 12320 cm³.
