Question

What is the curved surface area of a cylinder if its height and radius are 8 cm and 2 cm respectively?

• A. 16π sq cm
• B. 24π sq cm
• C. 20π sq cm
• D. 32π sq cm

Answer 1

The correct option is D 32π sq cm

Curved surface area of a cylinder
$=2\pi rh$,
where r is the radius and h is the height.

So, curved surface area of the cylinder
$=2\times \pi \times 2\times 8=32\pi sqcm$
