Is my a) correct? And help me to understand b and c

1) (10pt) a) Sketch the graphs of the cardioid r = 2 + 2cos 0, and the circle r = 1 f ( 0 ) 2 2+ 2(080 ( 2 ) f ( - 0 ) = 2+ 2(08( -9 ) V symmm . about palem anis = TT - TT : D 7: 32x2+2 =13+2 21212 =12+2 2 .2 2: 2X2+2= 3 2 lat 7 : 2 CorS : 2-52 b) Find the angles of intersection of the two curves by setting 2 + 2 cos 0 = 1 c) Set up but do not solve an integral representing the area of the region inside the circle r = 1 and outside the cardioid r = 2 + 2 cos 0
