## Homework Statement

Find

[tex]\int{\int_{D}x dA}[/tex]

where D is the region in Q1 between the circles x

^{2}+y

^{2}=4 and x

^{2}+y

^{2}=2x using only polar coordinates.

## The Attempt at a Solution

Well, the two circles give me r=2 and r=2 cos [tex]\theta[/tex], and the integrand is going to be r

^{2}cos [tex]\theta[/tex], but I have no idea how to determine the bounds of integration in this case.
