How to Determine the Length of an Arc

Once you have all of this information, you can plug it into the following formula: L = r*θ Where L equals arc length, r equals radius, and θ equals central angle. For example, let’s say we have a

How to Find Arc Length: 10 Steps (with Pictures)

An arc length is just a fraction of the circumference of the entire circle. So we need to find the fraction of the circle made by the central angle we know, then find the circumference of the total circle made by the radius we know. Then we just

Length of an Arc

The length of an arc depends on the radius of a circle and the central angle θ. We know that for the angle equal to 360 degrees (2π), the arc length is equal to circumference. Hence, as the proportion between angle and

Arc length, how to calculate

You need to know the measurement of the central angle that created the arc (the angle of the two radii) to calculate arc length. The arc length is the fractional amount of the circumference of the circle. The circumference of any circle is
