Answer» Radius of ball which is melted = 3cm Radius of first formed ball = 1.5 cmRadius of second formed ball = 2 cmLet Radius of third formed ball = r cm Volume of large ball = sum of volume of 3 formed balls⇒4π/3 × 3³ = 4π/3(1.5³ + 2³ + r³)⇒ 3³ =1.5³ + 2³ + r³⇒ 27 = 3.375 + 8 + r³⇒ r³ = 27 - 8 - 3.375 = 15.625⇒ r = ∛15.625⇒ r = 2.5cm ∴Radius of third ball is 2.5cm |
