if side of square is , diagonal
diagonal divides square in two equal parts, as shaded surface as well
the area of the arc with center at point is:
area of the square equal to
=>
the area of the arc minus area of the square will be of the shaded surface:
to get the shaded surface, multiply by
-> approximately
