please attempt both questions a and b

The double integral , xydxdy is defined as the forger of the two regions R above the x -. axis bounded by the curves x" + 27 2GE (a) Using a transformation to polar coordinates the Integral becomes of the form: a J. sin(cB)de ['r'dr Specify the values of the following variables, corresponding to those highlighted in red above (enter answers 2. b = 3. C = 4. d 5. e = 6. 1= (b) Hence evaluate the integral in (a) above and enter the answer in the box below. flexydxdy =
