No clue on how to approach this problem, this info is all that's given: $$2\leq r \leq 3+2\cos(\phi)$$
Assignment is to sketch the region W and determine the area of this region. It is given in polar coordinates. What I've done so far is set $2$ equal to $3+2\cos(\phi)$, returning a value of $\phi=2\pi/3$. How do I continue from this point?
