Question

The formula for lateral surface area of a cylinder of radius 'r' and height 'h' is

• A. $\pi r^{2}h$
• B. $\pi rh$
• C. $\pi rl$
• D. $2\pi rh$

Answer 1

The correct option is D $2\pi rh$

Lateral surface area (or curved surface area) of a cylinder is the area of the curved surface that connects the base and the top.
Curved surface area of a right circular cylinder of radius 'r' and height 'h' is given by $2\pi rh$.
