How to Find Arc Length?

Use the steps given below to find the Arc length of the given arc.

Step 1: Note the central angle and length of the radius of the given arc.

Step 2: Use the arc length formula given above according to the value of the angle in degrees or radians.

Step 3: Simplify the above equation to get the required answer.

Arc Length

Arc Length is defined as the distance between the two points placed on the circle’s circumference and measured along the circumference. Arc length is the curved distance along the circumference of the circle. The length of the arc between two points is always greater than the chord between those two points.

Arc length of a circle can be calculated with the radius and central angle using the arc length formula, L = θ × r, where θ is in radians. Length of an Arc = θ × (π/180) × r, where θ is in degree.

In this article, we will learn about, Arc Length, Arc length Formula, Arc length Examples, and others in detail.
