Question

The curved surface area of the cylinder is $2\pi rh$ where as surface area of the cylinder is

• A. $\pi r(r+h)$
• B. $\pi rl(r+h)$
• C. $2\pi r(r+h)$
• D. $2\pi r^{2}l(r+h)$

Answer 1

Answer: (C)

$2\pi r(r+h)$

The curved surface area of the cylinder is $2\pi rh$ where as surface area of the cylinder is $2\pi r(r+h)$.
Surface area includes curved surface area and two circular bases of the cylinder.
