What is the Arc Length Calculator & How does it work?
The arc length of a circle is the distance along the curved line making up the arc. It can be calculated using the formula:
L = r theta
L = Arc Length, r = Radius of the circle, theta = Central angle in radians
For a curve, the arc length can be found using integration if the function defining the curve is known. However, for simplicity, this calculator focuses on circular arcs.

Frequently Asked Questions
How do I calculate the arc length of a circle?
Multiply the radius of the circle by the central angle in radians.
What is the formula for arc length?
The formula for arc length is L = rΞΈ, where L is the arc length, r is the radius, and ΞΈ is the central angle in radians.
Can I use degrees instead of radians?
Yes, but you'll need to convert degrees to radians first using the formula: radians = degrees Γ— (Ο€/180).
What is the arc length if the radius is 5 and the angle is Ο€/2 radians?
The arc length would be 5 Γ— Ο€/2 = 2.5Ο€ units.
How does this calculator work for different shapes?
This calculator specifically works for circular arcs. For other shapes, you may need to use integration or a different formula.
