Show answer & explanation
Correct answer: B. 25 : 64
Explanation
Volume ∝ r²h, and radii are in the ratio 4 : 5. So (16/25) × (h₁/h₂) = 1/4, giving h₁/h₂ = 25/64. The ratio is 25 : 64.आयतन ∝ r²h और त्रिज्याओं का अनुपात 4 : 5 है। अतः (16/25) × (h₁/h₂) = 1/4, जिससे h₁/h₂ = 25/64। अनुपात 25 : 64 है।More Mathematics & Numerical Ability questions
