Arc length of circle finder

This app will give with in second whats is the arc length of circle and circumference of circle, with the help radios and angle of the circle


An arc of a circle is a "portion" of the circumference of the circle.

The length of an arc is simply the length of its "portion" of the circumference. Actually, the circumference itself can be considered an arc length.

Definition: The distance along the curved line making up the arc


Arc Length

Definition: The distance along the curved line making up the arc
(See also Angle measure of an arc.)
Try this Drag one of the orange dots that define the endpoints of the blue arc. The arc length will be continuously calculated.

The arc length is the measure of the distance along the curved line making up the arc. It is longer than the straight line distance between its endpoints (which would be a chord)

There is a shorthand way of writing the length of an arc: This is read as "The length of the arc AB is 10". The lower case L in the front is short for 'length'. However, in many cases the letter L and even the curved line over the AB is left out if there is no doubt about what is meant.
