What is the relationship between the region enclosed by the circle and the region enclosed by the square? Think about it. (Hint: If you are trying to find the areas being mentioned in the question, you are making the problem much harder than it needs to be.) –  Braindead Nov 4 '12 at 18:47

The area of the square and circle are equal. Use this to find the radius of the circle.
