Question

The radius of the base of a right circular cylinder is $3cm$ and height is $7cm$. Find the curved surface area (in sq. cm.)

Answer 1

Given, radius $r=3cm$ and height $=h=7cm$

Curved Surface Area of a Cylinder of Radius $r$ and height $h$ $=2\pi rh$

Hence, curved surface area of the given cylinder $=2\times \frac{22}{7}\times 3\times 7=132$ sq.cm
