^{2 = volume \ height = 72\11 = 6.54}radius = 6.54

^{0.5 = 2.558 inches}diameter = 2 * radius = 5.116 inches

_{Asking other people to do your homework is called cheating.}^{2}* l), so swapping this around a bit, theradiusis sqrt( V / (pi * h)).Putting in your values : r =sqrt(72 / (pi * 11)) = 1.443 inches.

So the diameter is twice that . . .

2.886 inches.^{(No doubt some smarty pants will answer this with all the correct symbols shown ;¬)}
