Let Volume of sphere be V and Radius R
V = 4/3 pi R^3
if the Diameter is decreased by 25% the new Radius = 3 R/4
New volume = 4/3 pi (R3/4)^3 = 4/3 pi R^3 (3/4)^3 = V 27/64
V = 4/3 pi R^3
if the Diameter is decreased by 25% the new Radius = 3 R/4
New volume = 4/3 pi (R3/4)^3 = 4/3 pi R^3 (3/4)^3 = V 27/64
