hi Hannibal lecter

If the four corners of a square touch the circumference of a circle then the diagonal of the square must be the diameter of the circle.  So use Pythag. to calculate the diagonal and half it to get the radius.

If it's the other way round and the circle touches the sides of the square, then the length of the side is the diameter of the circle.
