## 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.

What is sector in drawing?

The terms industry and sector are often used interchangeably to describe a group of companies that operate in the same segment of the economy or share a similar business type.

What does sector mean in a non mathematical context?

Definition: The part of a circle enclosed by two radii of a circle and their intercepted arc. A pie-shaped part of a circle. As you can see from the figure above, a sector is a pie-shaped part of a circle. …

### 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.
