What is the curved surface area of cylinder whose radius is 3 cm and height is 14 cm? (Take )
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 264 cm2.
CSA = 2πrh
radius (r) = 3 cm
height (h) = 14 cm
⇒ CSA = 2 × 22/7 × 3 × 14
⇒ CSA = 2 × 22 × 3 × 2
⇒ CSA = 264 cm2
