9 spheres of the same size are made from melting a solid cylinder of 8 cm diameter and 48 cm height. What is the diameter of each sphere?	Choose the correct choice from the following choices
A) 4 cm	B) 6 cm	C) 8 cm	D) 10 cm	E) 12 cm
Volume of cylinder = pi*r^2*h   Volume of a sphere = 4*pi*R^3 / 3   9*4*pi*R^3 / 3 = pi*r^2*h   R^3 = r^2*h / 12 = 64 cm^3   R = 4 cm   D = 8 cm   The answer is 8 cm.
