Correct answer: C. 1 : 2√2
Explanation
Surface area varies as r², so r₁² : r₂² = 1 : 2 gives r₁ : r₂ = 1 : √2. Volume varies as r³, hence V₁ : V₂ = 1³ : (√2)³ = 1 : 2√2.पृष्ठीय क्षेत्रफल r² के अनुपात में होता है, अतः r₁² : r₂² = 1 : 2 से r₁ : r₂ = 1 : √2। आयतन r³ के अनुपात में होता है, अतः V₁ : V₂ = 1³ : (√2)³ = 1 : 2√2।More Mathematics & Numerical Ability questions
