Question

Two edges of a rectangular sheet of paper having dimensions 14m $\times$ 7m are held together so that it forms a cylinder. Find the curved surface area(in sq. cm) of the cylinder.

• A. 98

Answer 1

The correct option is A 98
Since the paper is formed into the cylinder, the area of paper is equal to the curved surface area of the cylinder.
Curved surface Area
= 2$\pi$r x h
= length of paper x breadth of paper
$=14m\times 7m=98m^2$
