A sector of a circle is the area bounded by two radii and the arc between the endpoints of the radii. The area of a sector is a fractional part of the area of the circle, just like arc length is a fractional portion of the circumference

Step-by-step explanation:

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

.Perimeter of a Sector

The perimeter of the sector of a circle is the length of two radii along with the arc that makes the sector.
