A name which has nothing to do with this question (well almost nothing)

What percentage of the circle is shaded? (The quadrangle shown in the picture is a square with one of the vertices in the circle's center.)

I don't see what so special and hard about this problem. Is so easy. In fact too easy. Immediately after seeing it, I knew it was 25%. I began to think it was a trick question of some sort, when actually, it wasn't.
