The curved surface area of a right circular cylinder of base radius 3 cm is 94.2 cm². The volume (in cm³) of the cylinder is (Take π = 3.14)
- A.138.6
- B.141.3✓ Correct
- C.125.6
- D.113.04
CSA of cylinder = 2πrh = 94.2. With r=3, π=3.14: 2 × 3.14 × 3 × h = 94.2 → 18.84h = 94.2 → h = 5 cm. Volume = πr²h = 3.14 × 9 × 5 = 141.3 cm³.
