Question

If radius of a cylinder is $14$ $cm$ and height is $10$ $cm$, find the area of its curved surface. $(\pi =\frac{22}{7})$

Answer 1

Curved surface area of cylinder $=2\pi rh$
Given, $r=14$ $cm$, $\pi =\frac{22}{7}$ and $h=10$ $cm$
Curved surface area of cylinder $=2\times \frac{22}{7}\times 14\times 10$
$=44\times 2\times 10$
$=880$ $c{m}^2$.
