Question

If the circumference of the base of a solid right circular cylinder is $154$ cm and its height is $16$ cm, then find its curved surface area.

Answer 1

Circumference of the base of cylinder $=154$ cm
Therefore, $2\pi r=154$
Height $h=16$ cm
Curved surface area of cylinder $=2\pi rh$ sq.cm.
$=154\times 16$
$=2464c{m}^2$

Therefore, curved surface area of cylinder is $2464c{m}^2$.
