SectorSegmentArea of a SectorWe can work out the Area of a Sector by comparing its angle to the angle of a full circle.Note: we are using radians for the angles.This is the reasoning:A circle has an angle of 2π and an Area of:πr2 A Sector has an angle of θ instead of 2π...

If the points A, B, and O are collinear, the segment AB is a diameter and the circle is divided in two regions with equal area. Otherwise, one of the circular sectors will have smaller area and, for that reason, is going to be called the minor sector. The other, as expected, is ...
circle is a section of a circle that has the form of apieand is created by combining thearcof a circle with two of its radii. A sector is formed when a segment of thecircumferenceof a circle, also referred to as anarc, and two of the circle’sradiimeet at bothendpointsof the arc...
A sector is a geometric figure bounded by two radii and the included arc of a circle. Sectors of a circle are most commonly visualized in pie charts, where a circle is divided into several sectors to show the weightage of each segment. The pictures below show a few examples of circle sec...
Another characteristic of a sector is the chord, which is the line that connects the two points where the radii intersect the arc. The chord subdivides a sector into atriangleand asegment. To calculate the area of a sector, a simple formula can be used. ...
Circle, sector, segment, string and arc length, area online formula calculator Lines AO and OB are called radii. Lines AC, BC and AB are called strings. The angle ABC is an inscribed corner. The angle AOB is the central angle.
