square circumscribed by a circle
length of square = 2
so diagonal = 2sqrt2
1/2 diameter = 1/2 * 2sqrt2
radius = sqrt2
area of circle = pi*(sqt2)^2
area = 2pi
..
circle circumscribed in a square
1/2 diagonal of square = sqrt2
1/2 the side = 1
(sqrt2)^2-1^2= radius of cicle ^2
2-1=radius squared
1 = radius
area of circle = pi*1^2
=pi
ratio = 2pi/pi
=2
