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.
A cross section, I believe
It is a sector of the circle
They are the shapes of the slices when you slice a cone. For example, when you slice it parallel to the base and look at the shape of the slice, you see the conic section known as a "circle". The others are the "ellipse", the "parabola", and the "hyperbola". Which one you get depends only on how you tilt the knife when you slice the cone.
It is a sector
A region of a circle called a pie slice is also called a sector. The sector is one of the main slices of a circle, the other is called a segment.

A slice (Pie) Octant

A slice of bacon is known as a rasher.
It is a sector of the circle
a slice
A slice, a segment or a sector.----------------A segment is the area of a circle between the chord and the arc. A "sector" is what you are looking for. See the links below.
A semicircle

The hedgehog slice is called the hedgehog slice because it looks like a hedgehog.
A sector is a part of a circle, like a slice of pie.
