Question

A solid right circular cylinder has a radius of $8cm$ and a height of $14cm$. Find its curved surface area.

• A. $704{cm}^2$
• B. $735{cm}^2$
• C. $74{cm}^2$
• D. None of these

Answer 1

The correct option is A $704{cm}^2$

We have,

$h=14cm,r=8cm$

We know that the curved surface area of the cylinder is

$=2\pi rh$

Let $S$ be the required curved surface area

$S=2\times \frac{22}{7}\times 14\times 8$

$=704c{m}^2$

Hence, (A) is the correct option
