pi r^2=s^2
pick a number let's assume s=2
s^2=4 diagonal =2 sqrt2
pi r^2=4 r=sqrt(4/pi) diameter=2*sqrt(4/pi)
diag/diameter is approximately 1.2
So, answer B would be the closest answer.

Consider D = dia of circle
S = Diagonal of square
s = side of square
s^2 + s^2 = S^2
2s^2 = S^2
s^2 (area of square) = (S^2)/2

Area of circle = (Pi/4)D^2

equating Areas we get S^2/D^2 = Sqrt(Pi/2)

= 1.252
Appox 1.26 (B)
