WebAug 7, 2024 · Calculation: Radius of the original ball be R. Volume of the original sphere = 4/3 × π × R 3. Ratio of the diameter of two new sphere balls is 1 : 2, therefore the ratio of the radius of two new sphere balls be R 1 : R 2 = 1 : 2. R1 : R2 = 1 : 2, ∴ R2 = 2R1. Smaller ball radius = R 1 and Bigger ball radius = R 2.
