Question

Formula of C.S.A OF CYLINDER

Answer 1

The formula of C.S.A (curved surface area) of a cylinder is $2\pi r h$

The cylinder consists of two circles as the base and top.

Circumference of circle is

$2\pi r$

Let the height of cylinder be (h)

So the C.S.A is

$2\pi r \times h$

= $2\pi rh$

Hope it helps:)
