as far as i think there will be twom circles made one with centre point 0,0 and modz = z-(0 +0i)
the second circle would be mid z-2 take it in general form ul get z- (2+0i) so 2 and zero as centre point.
this must be satisfied that the shaded region wud be in accordance with the in equality
the second thing is argument ... the region wch will be shaded will be between 0 and pi/4...
i no thisisnt a satisfactory explanation... but i have forgotten this chater completely ...
