The circle shown has four equally-spaced diameters of length 2 cm. What is
the length of the longest path that can be drawn in one continuous pen
stroke from A to B without retracing and without having the path cross
itself? (The path may meet itself only at the center but may not cross over
itself.) Express your answer in terms of π.
