Sector
Yes.
An arc is a portion of the circumference of a circle, defined by two endpoints on the circle. In contrast, a sector is a region enclosed by two radii and the arc connecting them, resembling a "slice" of the circle. Essentially, while an arc is just the curved line, a sector includes the area bounded by the arc and the radii.
The region bounded by an arc and a chord is known as a "segment" of a circle. This segment includes the area enclosed by the chord and the arc connecting the endpoints of the chord. The segment can vary in size depending on the length of the chord and the curvature of the arc. If the chord is a diameter, the segment is known as a semicircle.
The area of the shaded region is 1265.42 meters squared, since I subtracted the two totals of both the unshaded region and the shaded region of a circle.
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.
sector
Yes.
No, the region enclosed by a circle is not considered convex because it contains points within the circle that do not lie on the boundary of the circle. In convex regions, any line segment connecting two points inside the region will also lie completely inside the region.
A sector of a circle is the region enclosed by two radii and the circumference. If you draw a picture, you can see that there are actually two regions formed. One has an angle of 180 degrees or less at the center, and the other has an angle of 180 degrees or more. A sector which occupies more than half of the circle is a major sector. To put it more succinctly, a major sector is enclosed by two radii and a major arc of a circle.

the set f all points of the plane which lie either on the circle or inside the circle form the circular region
The region between the Arctic Circle and the North Pole is called the Arctic region. The region between the Antarctic Circle and the South Pole is called the Antarctic region.
A circular region or a disk.
No. A fundamental region is usually a circle.
Estuary
A segment or a sector are both regions in a circle.
