**2. Homework Equations**

**3. The Attempt at a Solution**

I first drew R, and from the circle equation, I know the radius of the circle is 12.5. Since the region is in the first quadrant, that'll mean that my limits of integration for r and theta would be[tex]\int^{2\pi}_{0}\int^{12.5}_{0}[/tex]

I'm getting confused on how to do the actual integration. My professor said to integrate by parts, but I'm still getting confused when doing it.
