1) A garden is laid out as a set of four half circles, see
diagram. The ratio of the diameters of the three smaller
circles is 2 to 1 to 3. What is the ratio of the distance for
walking from A to B along the outer edge of the single large
circle compared to the distance for walking from A to B along
the outer edges of the three smaller circles?
