Volume = Pi * radius2 * height
radius2 = volume \ height = 72\11 = 6.54
radius = 6.540.5 = 2.558 inches
diameter = 2 * radius = 5.116 inches

Stupid formatting. You get the picture :)

Too bad "CHEAT" isn't one of the flag options.

The volume of a cylinder the area of the base times the length (v = pi * r2 * l), so swapping this around a bit, the radius is 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.
