I am really struggling on this problem  geometry
posted by Knights on .
Please help guys if you can, this is a really hard problem I am trying to solve
Four circles of unit radius are drawn with centers (1,0),(0,1) ,(1,0) ,(0,1) and . A circle with radius 2 is drawn with the origin as its center. What is the area of all points which are contained in an odd number of these 5 circles? (Express your answer in the form "a pi + b" or "a pi  b", where a and b are integers.)

Not sure what you are asking for
There is only one point (0,0) that contains all 5 circles 
I worked this out a while back:
