Answer 2

Answer:  1760Cm²

-----------------------------------------------------------------------------------------------------------------

Given:-

Diameter of cylinder ( D ) = 28Cm.

Radius of cylinder ( R ) $= \frac{d}{2} =14 cm$

Height of cylinder ( H ) = 20Cm.

As we know that, curved surface area of cylinder is given as-

$csa = 2\pi rh = 2 * \frac{22}{7} *14 * 20 = 1760cm^{2}$
