The volume of sphere = 4/3 x 3.14 x R^3 = 4851
Hence radius R = (4851 x 3/4 / 3.14)^1/3
R^3 = 1159
R = 10.5 cm
Final volume = 4351/3 = 4/3 x 3.14 x X^3
4351 /12.56 = X^3
X^3 = 346
X = 7 cm
Reduction in radius = 10.5 - 7 = 3.5 cm
Hence radius R = (4851 x 3/4 / 3.14)^1/3
R^3 = 1159
R = 10.5 cm
Final volume = 4351/3 = 4/3 x 3.14 x X^3
4351 /12.56 = X^3
X^3 = 346
X = 7 cm
Reduction in radius = 10.5 - 7 = 3.5 cm
