The diameter will be the same as the diameter of the cylinder because the balls fit inside the cylinder
Do you mean V = (128/9)pi?
V = pi*r^2*h = (128/9)pi.
3.14*r^2*8 = 44.7
r^2 = 1.78
r = 1.33 In.
D = 2r = 2.7 In.
V = pi*r^2*h = (128/9)pi.
3.14*r^2*8 = 44.7
r^2 = 1.78
r = 1.33 In.
D = 2r = 2.7 In.
