A Pi Day Puzzle

Today is Pi Day. So here is a Pi Day Puzzle.

A square and a circle both have an area equal to pi.
Their centres are at the same point.
What is the area of the region of overlap?

Also try the Pi Day Challenge.

And I have also set up a Pi Day Challenge 2013 community at G+
(This will stay open for about a month)
