(will mark best answer)two circles are shown in the diagram. since all circles are similar, a proportion can be set up using the circumference and diameter of each circle. substitute the values d1 = 1, c1 = π, and d2 = 2r into the proportion. c1/d1 = c2/d2 which shows how to correctly solve for c2, the circumference of any circle with radius r?
