Question 570872: Two cylindrical cans have the same volume. The height of one can is triple the height of the other. If the radius of the narrower can is 12 units, how many units are in the length of the radius of the wider can. I drew a picture to represent the 2 cans. I know that volume of can a=volume of can b. I know the height of can a=3b. I know the radius of can a is 12 units. I know the volume of a cylinder is pi (r)squared (h). I don't know what to do next.

pi * 12^2 * 3h = pi * r^2 * h

dividing by (pi * h) ___ 12^2 * 3 = r^2
