13 Nov 2007, 05:24

The area of a circle is equal to the area of a square. Which of the following is closest to the ratio of the diag of the sq to the diameter of the circle?

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.
