Curves C1 and C2, region R, and point Q are given as follows:

Set up, but do not evaluate, the integral or sum of integrals for the following:
(a) the perimeter of R
(b) the area of R

Let Ci be the circle r = cos 0.
The graph of r = v3 cos(20) is an example
of a polar curve called a rose. Let C2 be
the petal of the rose r = v3 cos(20) that
is to the right of the -axis, as shown in
the figure. Its portion on and above the
polar axis is traced from right to left as 0
increases.

• Let R be the region that is above the polar
axis, inside the curve C1, and outside the
curve C2, as shaded in the same figure.
• Let Q be the point with polar coordinates
