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

Back to Top
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 × $\frac{central   angle}{360}$

  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.



    Answer  :  

    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



    Answer  :  

    14.67 cm
