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 re: If 25pc of the Square is shaded... by tomarken)

I would not trust the special symbol button to work. I try to avoid symbols in comments. I note that the comment to which I'm replying has several symbols that did not come out looking right, in either Internet Explorer or Chrome.
