Question

The radius of a cylinder is 8 cm and its height is 35 cm. What is the area of its curved surface?

Answer 1

Radius of cylinder (r) = 8 cm
Height of cylinder (h) = 35 cm
Curved surface area of cylinder = 2πrh
$$\begin{gathered} =2\times \frac{22}{7}\times 8\times 35 \\ =1760\mathrm{sq}\mathrm{cm} \end{gathered}$$
