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.)

(In reply to The drawing by lucky)

And what TomM said about the vertex of the quadrilateral being the center of the circle.....
