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 of the cylinder.

• A. 98$m^2$
• B. 78$m^2$
• C. 88$c{m}^2$
• D. 100$c{m}^2$

Answer 1

The correct option is A

98$m^2$

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 $=14m\times 7m=98m^2$
