Arc Length is the distance along the curved line making up the arc. Online Arc Length Calculator is a tool which makes calculations easy and fun. It is used to calculate the arc length when the radius of the arc and the central angle of the arc in degrees are given. Try our Arc Length Calculator and get your problems solved instantly.

## Steps for Arc Length Calculator

Step 1 :

Observe the radius of the arc and the value of central angle and take value of "π" as 3.142 or 22/7.

Step 2 :

Apply the formula Length of an arc = 2 × π × r × $\frac{central angle}{360}$

## Examples on Arc Length Calculator

1. ### Find the length of an arc of a circle having radius 7 cm and central angle 30 degrees?

Step 1 :

Here, radius = 7cm central angle= 30 degrees

Step 2 :

Length of an arc = 2 × π × r × $\frac{central angle}{360}$ = 2 × π × 7 × $\frac{30}{360}$ = 3.67 cm.

3.67 cm

2. ### Find the length of an arc with radius 14 cm and central angle 60 degrees?

Step 1 :

Here, radius = 14 cm central angle = 60 degrees

Step 2 :

Length of an arc = 2 × π × r × $\frac{central angle}{360}$ = 2 × π × 14 × $\frac{60}{360}$ = 14.67 cm
