Question

Find the curved surface area of a cylinder whose base radius is 14 m and height is 30 cm.

Answer 1

Radius of cylinder, r = 14 m =1400 cm
Height of cylinder, h = 30 cm
$$\begin{gathered} \mathrm{Curved}\mathrm{surface}\mathrm{area}\mathrm{of}\mathrm{cylinder}=2\mathrm{\pi }rh \\ =2\times \frac{22}{7}\times 1400\times 30 \\ =264000{\mathrm{cm}}^2 \end{gathered}$$
