Question : What will be the curved surface area of a cylinder having a radius of 20 cm and a height of 34 cm?(use $\pi$ = 3.14)
Option 1: 3245.7 cm2
Option 2: 4328.98 cm2
Option 3: 4270.4 cm2
Option 4: 4320.6 cm2
Correct Answer: 4270.4 cm 2
Solution :
The curved surface area of a cylinder with radius $r$ and height $h$ is $2\pi rh$.
Given, radius($r$) = 20 cm and height($h$) = 34 cm
So, the curved surface area of the cylinder
= $2\pi rh$
= 2 × 3.14 × 20 × 34
= 4270.4 cm
2
Hence, the correct answer is 4270.4 cm
