The lateral surface area of a cylinder is 3862.2 cm2 and its height is 15 cm. Find its volume correct to one decimal place. (take π = 3.14)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 79175.1 cm3.
Lateral surface area(LSA) = 2πrh
here, r = radius, h = height
⇒ 3862.2 = 2 × 3.14 × r × 15
⇒ r = 41 cm
Volume = πr2h
⇒ 3.14 × 41 × 41 × 15 = 79175.1 cm3
