Determine by direct integration the moment of inertia about the y-axis in the figure shown.

2. Relevant equations

See Iy on attached.

Equation for curve also on attached.

3. The attempt at a solution

My answer didn't include pi, and the answer apparently does. I'm trying to do this via a double integral as opposed to using one integral and doing something funky. My problem I THINK is in finding dA.
