What is Meant by Arc Length?

In Mathematics, the length of the arc is determined by using the radius and the central angle θ(either in degrees or radians). It is known that when the arc length is equal to the circumference of the circle, the angle is equal to 360° (2π). In this case, the proportion between the central angle and the arc length is constant, and the arc length formula is given as
Arc length, L = r × θ
Similarly, we can find the area of a sector of a circle. From the proportion, the area of a sector is defined by
Area of the sector, A = r2/(θ/2)
