hmm … that's \int_0^2\int_0^{\sqrt{2x-x^2}}\sqrt{x^2+y^2} dxdy
ok … I assume you know how to convert dxdy into r and θ
and for the limits, convert y2 ≤ 2x - x2 into r and θ also :wink:

0≤y≤1
0≤x≤2
0≤r≤2
0≤θ≤ pi/2

(have a pi: π :wink:)
No, the upper limit of r will depend on θ.
I repeat … convert y2 ≤ 2x - x2 into r and θ
