A unit circle has a radius of 1, giving it a diameter of 2. (Right
triangles inscribed inside a unit circle are the basis of
trigonometry.) If the square goes around the circle, each of its sides
is 2. If the square is inside, its diagonal is 2 and each of its sides
is sqrt(2).

So a circle *circumscribed* (as opposed to inscribed) around the
unit square would have a radius of sqrt(2)?
