Circle \(1,\) Circle \(2,\) and Circle \(3\) have the same center and have a radius \(r_1<r_2<r_3.\) Let \(A_1\) be the area of circle \(1,\) let \(A_2\) be the area of the region within Circle \(2\) and outside Circle \(1,\) and let \(A_3\) be the area of the region within Circle \(3\) and outside Circle \(2.\) What are the values \(\dfrac{A_1}{A_2}\) and \(\dfrac{A_2}{A_3}?\)

(1) \(A_2=A_3\)

(2) \(A_2+A_3 = 2 A_1\)
