Question:

The radius of the base of a cylinder is 14 cm and its volume is 6160 $cm^3$, The curved surface area (in $cm^2$) is:

(Take $\pi = \frac{22}{7}$)

Options:

778

880

660

940

Correct Answer:

880

Explanation:

We know that,

The curved surface area of cylinder = 2πrh

Volume = πr2h

Radius = 14 cm

The curved surface area = 880 cm2

According to the question,

 2πrh = 880

= 2 × \(\frac{22}{7}\) × 14 × h = 880

= h = 10 cm

The volume of the cylinder = \(\frac{22}{7}\) × (14)2 × 10 = 6160 cm3
