Homework Help: Math Geometry

Posted by 3.1415926... on Saturday, August 3, 2013 at 5:41pm.

Four circles of unit radius are drawn with centers (1,0), (-1,0), (0,1), and (0,-1). 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.)

I want a clear explanation with the answer. Thanks!
