    I never knew how to do ratio between a circle and a square. Helpful to now know the formula. One side of square is x and r is the radius of the circle. Formula to get r squared is x/2 squared plus x/2 squared. Figure out r. Square area equals length times width and circle equals Pi times r squared. Divide area of square by area of circle and the answer is 2/Pi.

    There is a simpler solution: The square is two triangles with base 2r and height r, that is 2*squared(r). The area of circle is pi*squared(r).The requested ratio is the square area divided by the circle area, that is: 2/pi
