Sector
Yes.
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.
yes!
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.
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
sector
Yes.
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.
Segment
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.
the set f all points of the plane which lie either on the circle or inside the circle form the circular region
A circular region or a disk.
Estuary
No. A fundamental region is usually a circle.
A segment or a sector are both regions in a circle.
The Plot Area.
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.
