Question : What is the curved surface area (in cm2) of a cylinder having a radius of base as 14 cm and height as 10 cm?
Option 1: 440
Option 2: 880
Option 3: 220
Option 4: 1320
Correct Answer: 880
Solution : Given: r = 14 cm and h = 10 cm The curved surface area of a cylinder $= 2\pi rh$ The curved surface area of a cylinder $ = 2\times\frac{22}{7} \times 14 \times 10 = 880\, \text{cm}^2$ Hence, the correct answer is 880.
