define the term sector of a circle?
Answers
A circular sector or circle sector (symbol: ⌔), is the portion of a disk enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger being the major sector.
Step-by-step explanation:
A circular sector or circle sector (symbol: ⌔), is the portion of a disk enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger being the major sector.[1]:234 In the diagram, θ is the central angle, {\displaystyle r}r the radius of the circle, and {\displaystyle L}L is the arc length of the minor sector.The minor sector is shaded in green while the major sector is shaded white.A sector with the central angle of 180° is called a half-disk and is bounded by a diameter and a semicircle. Sectors with other central angles are sometimes given special names, these include quadrants (90°), sextants (60°) and octants (45°), which come from the sector being one 4th, 6th or 8th part of a full circle, respectively. Confusingly, the arc of a quadrant can also be termed a quadrant.The angle formed by connecting the endpoints of the arc to any point on the circumference that is not in the sector is equal to half the central angle.[
