The lateral surface area of a cylinder is 352 cm2 . If its height is 7 cm, then its volume (in cm3) is? (Take π = 22/7)
Show answer & explanation
Correct answer: A
Explanation
The correct anwer is option 1 i.e. 1408 cm3.
L.S.A. = 2πrh = 352
2 × 22/7 × r × 7 = 44
44 × r = 352
r = 8
V = πr2h = 22/7 × 8 × 8 × 7
= 22 × 64 = 1408 cm3
