# Arc Length Calculator

Arc length is defined as the length along the arc, which is the part of the circumference of a circle or any curve. Online arc length calculator to find the arc length of a circle using radius and central angle values.

## Calculate Arc Length of a Circle

Code to add this calci to your website

#### Formula:

Arc Length of a Circle (S) = 2 x π x r (central angle/ 360)
**Where,**
r - Radius of arc
Arcs are measured in two ways: as the measure of the central angle, or as the length of the arc itself. Arc length of a circle is the distance measured as the length. The arc length formula is used to find the length of an arc of a circle. It depends on the radius of a circle and the central angle. The length of arc is equal to radius multiplied by the central angle (in radians). Enter the values of radius and center angle in this **arc length calculator** to calculate the length of the arc
of a circle.

### Example:

Consider that the radius of the circle be 5cm and the center angle be 30 degrees. Calculate the arc length of the circle from the given values.

#### Given:

Radius of the circle = 5cm

Center Angle = 30 Deg

#### Solution :

Apply the values in the formula,

Arc Length of a Circle = 2 x π x r (central angle/ 360)

= 2 x π x 5 (30/ 360)

= 2.619 cm
