Question

The total surface area of a cylinder = $2\pi rh+\pi r^2$

• A. True
• B. False

Answer 1

The correct option is B

False

A cylinder has 2 circular faces – one at the top and other at the bottom.
Therefore, total surface area = Curved Surface Area + sum of areas of 2 circular faces
$=2\pi rh+2\pi r^2$
$=2\pi r(h+r)$
