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.  Jorge Carlos V. 0 0 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  Khalid B. 1 0 5/2π  Khalid B. 0 0 3  Khalid B. 0 0 1  Khalid B. 0 0 0.25  Khalid B. 0 0 0.50  Linda E. 0 0 It was very helpful  Candance S. 0 0 I guess I was the only one who was lost by that whole equation  Hafid A. 0 0 G
