The perimeter of a circular segment is the sum of the arc length and the straight line segments that connect the endpoints of the arc to the chord. The formula to find the perimeter of a circular segment depends on the angle of the segment and the radius of the circle.

In real life, the perimeter of a circular segment is used in various applications such as designing circular arches for bridges or buildings, calculating the length of an arc in a circular race track, and determining the amount of fencing needed to enclose a circular section of land.

Calculating the perimeter of a circular segment can be useful in a variety of fields including engineering, architecture, physics, and geometry.

The formula for determining the perimeter of a circular segment is defined as:
