Consider the circle C1 : r = 1 and the roses C2 : r = cos 20 and C3 :r = 2 cos 20, each of which is symmetric with respect to the polar axis, the -axis, and the origin, as shown on the image. 2 0 1. Find polar coordinates (r, 0) for the intersection A of C1 and C3, where r, 8 > 0. 2. Set-up (do not evaluate) a sum of three definite integrals that give the perimeter of the yellow- shaded region inside both C1 and C3 but outside C. 3. Find the area of the unshaded region inside C; but outside C. KIN
