If base radius and height of a cylinder are increased by 10\% then its volume increased by -

  1. 30%

  2. 40%

  3. 42%

  4. 33.1%

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Original volume V = πr²h. After 10% increase: r' = 1.1r, h' = 1.1h. New volume V' = π(1.1r)²(1.1h) = π(1.21r²)(1.1h) = 1.331πr²h = 1.331V. Percentage increase = (1.331 - 1) × 100 = 33.1%.
