This arc length calculator is a tool that can calculate the length of an arc and the area of a circle sector. This article explains the arc length formula in detail and provides you with step-by-step …

Arc of a circle is a portion of its circumference. Thus, the arc length of a circle is a fraction of its circumference. If θ degrees is the central angle made by an arc of a circle, then the arc length …

Here you will learn about the arc length formula, including how to identify the arc of a circle (minor and major), form and use the arc length formula to calculate arc length, and calculate the arc …

Oct 13, 2025 · Arc length is the distance between one endpoint of an arc on a circle to the other. In this article, we’ll tell you what formulas you need and how to use them to find a circle's arc …

Whether you need to calculate the length of an arc, chord length, or other properties of a circle, our calculator is here to make your life easier. How to use the Calculator:

Part of the circumference of a circle. Or part of any curve. See an arc in action (drag the points): The arc length is: L = θ × r (when θ is in radians) L = θ × π 180 × r (when θ is in degrees)

Jul 23, 2025 · Arc length is calculated using the simple formula: Arc Length= r × θ where 'r' is the radius of the circle and 'θ' is the angle in radians. In this article, we have covered the Arc …

Aug 3, 2023 · Learn how to find the measure of the arc length of a circle with formulas and solved examples.

Find the circumference of the circle and then multiply by the measure of the arc divided by 360°. Remember that the measure of the arc is equal to the measure of the central angle. The …

So we need to find the fraction of the circle made by the central angle we know, then find the circumference of the total circle made by the radius we know. Then we just multiply them …
