Question
Consider the circle C :r = 4, and the limaçon
C2 :r = 3 – 2 sin 0. Note that both C1 and C2
are symmetric about the -axis. Let A and B be
the points of intersection of C1 and C2. Let R1
be the region within C1 but outside C2, and R2
be the region within both C1 and C2, as shown on
the right.
R1
1. Find polar coordinates (r,0) for A and B,
where r> 0 and 0 € [0, 27).
R2
2. Set up (and do not evaluate) the definite
integral/s that will give the following.
a. perimeter of R1
b. area of R2.
