What is the curved surface area of a cylinder having a radius of base of 70 cm and height of 14 cm?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 6160 cm²
Radius r = 70 cm
Height h = 14 cm
the curved surface area (CSA) of a cylinder = 2πrh
⇒ 2 × 22/7 × 70 × 14
⇒ 2 × 22 × 10 × 14 = 6160 cm²
