**Steve**, Saturday, August 3, 2013 at 5:54pmEach small circle has area pi

The intersections each have area pi/2 - 1, so the 4 areas of intersection have area 2pi-4

The large circle has area 4pi.

The points outside all the small circles lie only in the big circle.

the points in each of the intersections lie in 2 small circles and the big circle.

So, now you know which areas to add up.
