If the volume of a solid cylinder is 5236 cm3 and its height is 34 cm then, find its curved surface area (in cm2). (Take π = 22/7)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 1496.
The volume of a cylinder is 5236 cm3
And its height is 34 cm
Volume = 5236
⇒ πr2h = 5236
⇒ r2 = 49
⇒ r = 7
So, curved surface area = 2πrh = 2 × 22/7 × 7 × 34 = 1496 cm2
