Chapter 14.3, Problem 11ES

Let R be the region described. Sketch the region R and fill in the missing limits of integration.

${\displaystyle \underset{R}{\iint }f(r,\theta )dA={\displaystyle {\int }_{\boxed{}}^{\boxed{}}{\displaystyle {\int }_{\boxed{}}^{\boxed{}}f(r,\theta )rdrd\theta }}}$

The region inside the circle $r=4\sin \theta$ and outside the circle $r=2.$
