Solution

We know that the curved surface area of a right circular cylinder with radius $r$ and height $h$ is $C S A = 2 π r h$ .

It is given that the height is $h = 14$ cm and the radius is $2$ cm, therefore,

$C S A = 2 π r h = 2 \times \frac{22}{7} \times 2 \times 14 = 176$ cm $^{2}$

Hence, the curved surface area is $176$ cm $^{2}$ .
