Given the center of a circle and a point on the circle, you can use the distance formula d=sqrt%28+%28x%5B1%5D-x%5B2%5D%29%5E2+%2B+%28y%5B1%5D-y%5B2%5D%29%5E2%29 to calculate the radius. The diameter of a circle inscribed in a square is equal to the side length of the square. So, take the radius that you calculated, double it, and then square the result for the area of the square.
