Question

The radius of the base of a right circular cylinder is $4$ $cm$ and its height is $14$ $cm$, find the curved surface area.

Answer 1

Given, the radius of the base of a right circular cylinder is $4$ $cm$ and its height is $14$ $cm$.

Here, $r=4$ $cm$ and $h=14$ $cm$

Curved surface area of cylinder $=2\pi rh$

$=2\times \frac{22}{7}\times 4\times 4$

$=44\times 8$

$=352{cm}^2$

$\therefore$ the curved surface area of cylinder is $352{cm}^2$.
