The objective of this question is to use Green's theorem (in either form) to evaluate I = f a:2y d3: | 3/23: dy, C where C : (9D and D : {(m,y) l :1: 3 0,3; g 0,332+y2 g 7} is the quarter circle of radius 7. By rewriting the contour integral on 6D as a double integral on D, i.e., ~34 WNW-U 6D D (13113}: the contour integral is evaluated to be
