You divide the area of the shaded region by the area of the full circle. For example, if the radius of the shaded region is 2 meters, the probability would be 4pi / 36pi, or 1/9. If the shaded region is a 'slice' of the circle, the chance is just the fraction of the circle which the 'slice' is.
It ultimately depends on the areas of the two shapes: Acircle = pi*r2 Asquare = l2 Fraction shaded = Acircle / Asquare = pi*r2/ l2 If the circle fills the square (e.g. l=2r) then the formula simplifies considerably: pi*r2/4r2 = pi/4
The shaded parts
0. There is no circle so no shaded area of a circle!
I see no shaded part fo the fraction must be "none".
Only half of the circle would be shaded.
