## What is the definition of sector in geometry?

A sector is a region bounded by two radii of a circle and the intercepted arc of the circle. The angle formed by the two radii is called a central angle. A sector with a central angle less than 180° is called a minor sector. A sector with a central angle greater than 180° is called a major sector.

**What is the definition of sector area?**

The area of a sector of a circle is the amount of space enclosed within the boundary of the sector. A sector always originates from the center of the circle. The sector of a circle is defined as the portion of a circle that is enclosed between its two radii and the arc adjoining them.

### What is a sector or segment?

A sector is the part of a circle enclosed by two radii of a circle and their intercepted arc. The segment of a circle is the region bounded by a chord and the arc subtended by the chord.

### How do you find the sector?

The formula for sector area is simple – multiply the central angle by the radius squared, and divide by 2: Sector Area = r² * α / 2.
