The volume of a right circular cylinder is 1100 cm3 and the radius of its base is 5 cm. Calculate its curved surface area.
2 answers:
Answer: A
Step-by-step explanation: πr2 h = 1100 cm³
Here r = 5
(22/7) ⋅ (5)2 ⋅ h = 1100
h = 2/7
Curved surface area of cylinder = 2 πr h
= 2 ⋅ (22/7) ⋅ 5 ⋅ (2/7)
= 440 cm²
So, the curved surface area of cylinder is 440 cm²
