Consider the circle C1 : r = 4, and the limacon C2 : r = 3 - 2sin 0. Note that both C1 and C2 are symmetric about the ;-axis. Let A and B be the points of intersection of C, and C2. Let R1 be the region within Ci but outside C2, and R2 R1 be the region within both C, and C2, as shown on the right. 0 1. Find polar coordinates (r, 0) for A and B, where r > 0 and 0 c [0, 2x]. R2 B /A 2. Set up (and do not evaluate) the definite integral/s that will give the following. a. perimeter of R1 b. area of R2
