The curved surface area of a solid cylinder of height 15 cm is 660 cm2. What is the volume (in cm3) of the cylinder? (Take π\pi = 227\frac{22}{7})

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 2310.

Given that

The curved surface area of a solid cylinder of height 15 cm is 660 cm2

CSA of cylinder = 2πrh

The volume of the cylinder =  π r² h

⇒ CSA = 2 × (22/7) × r × 15

⇒ 660 = 660/7 × r

⇒ r = 7 cm

Volume of cylinder = (22/7) × 49 × 15 = 2310 cm3
