A cylindrical can is to have the area of its curved surface equal to thesum of the areas of its base and its top. What must be the relation between the height and diameter of this can?

The area of the curved surface of the can is 2{\pi}rh

The area of the two bases is 2{\pi}r^{2}

They must be equal:

2{\pi}rh=2{\pi}r^{2}

Now, find the relationship between r and h.
