SSC CPO Tier I - 12th March 2019 - Shift 1 • Quantitative Aptitude • Q138

The volume of a cylinder is 5236 cm3, and its height is 34 cm. What is its curved surface area (in cm2)?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 1496

The volume of a cylinder is 5236 cm2

and its height is 34 cm

then v = 5236

⇒ пr2h = 5236

⇒ r2 = (5236 × 7)/(22 × 34) = 49

⇒ r = 7 cm

So,

Curved surface area = 2пrh = (2 × 22 × 7 × 34)/7 = 1496 cm2
