In the world of mathematics and engineering, calculating the length of an arc plays a crucial role in various applications. Whether you’re designing a bridge, constructing a road, or programming a computer-aided design (CAD) software, understanding and accurately determining arc length is essential. This article explores the concept of ARC Length Calculator, its significance, applications, usage, and much more.

Understanding ARC Length

What is an arc?

An arc is a portion of a curve, typically a segment of a circle. It is defined by two points on the curve, known as the endpoints, and the points lying on the curve between these endpoints.

How is arc length calculated?

Arc length is the distance along the curved line making up the arc. It is calculated using the formula:

Arc Length=�×RadiusArc Length=θ×Radius

where �θ is the angle subtended by the arc at the center of the circle and the radius is the distance from the center of the circle to any point on the arc.
