You can put this solution on YOUR website!
1. What is the exact area of the square that the circle does not cover?
s = length of a side of the Square, r = radius of the Circle
A%5Bsquare%5D+-+A%5Bcircle%5D+=+s%5E2-+pi%2Ar%5E2
2. Find the area of a square whose sides are all tangent to the circle.
r = s/2
s = 2r
A%5Bsquare%5D+=+%282r%29%5E2
