Arc Length Calculator

Arc length can be defined as length of an arc which is a segment of a curve or it can also be segment of a Circle. Formula for calculating Arc Length when value of central angle and radius are known is given as shown below:
 
Arc length = 2 ∏ r (C / 360), where 'r' is the radius of arc, 'C' is the central angle of arc which is measured in degrees, value of '∏' is approximately equals to 3.14.
 
Arc length calculator is an online tool or calculator which can be used to calculate arc length when values of Radius and Central angle are known.
 
Steps to use arc length calculator are shown below:
 
Step 1: Enter radius of Arc in first text box.
 
Step 2: Enter Central angle of arc in degrees in second text box.
 
Step 3: Click on 'Solve' button and result will be displayed in 'Arc Length' text box.
 
Let us take an example:
 
Step 1. Enter radius of Arc as 10 inch in first text box.
 
Step 2. Enter Central angle as 450 in second text box.
 
Step 3. Click on 'Solve' button and result will be 7.854 inches.
