If the curved surface area of a cylinder is 126π cm2 and its height is 14 cm, what is the volume of the cylinder?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 283 1/2 π cm3
If the curved surface area of a cylinder is 126π cm2 and its height is 14 cm
the curved surface area of a cylinder = 126π
2 π r h = 126 π
r = 9/2 cm
The volume of the cylinder = π × r2 × h = π × (81/4) × 14 = (567/2) × π = 283 1/2 π cm3
