Question 429880: Jimmy has enough paint to cover a surface area of 1 square meter. If he paints a circular disk with the paint, what is the maximum radius of such a disk? If he chooses, instead, to paint a sphere with it, what is the maximum radius of the sphere?

The area of a circle = %28pi%29r%5E2
1 = %28pi%29r%5E2+-%3E+r+=+sqrt%281%2F%28pi%29%29
The surface area of a sphere = 4%28pi%29r%5E2
1 = 4%28pi%29r%5E2+-%3E+r+=+sqrt%281%2F4%28pi%29%29+-%3E+%281%2F2%29sqrt%281%2F%28pi%29%29
