A circle is inscribed in a unit square, and a diagonal of the square is drawn. Find the total
length of the segments of the diagonal not contained within the circle.  Choose the correct choice from the following answers:
A) √4-1  B) √2-1  C) √3-1  D) √5-1  E) √6-1
The diagonal has length √2.It passes through the center of the circle, so it contains   a diameter of the circle. The length of the diagonal within the circle is therefore 1. The rest of   the diagonal outside of the circle has total length √2-1   correct answer √2-1
