This is the arc length formula when the angle is in degrees. The length of an arc can be calculated using different formulas, based on the unit of the central angle of the arc. The measurements of the central angle can be given indegreesorradians, and accordingly, we calculate the arc l...
Another option is to use the Chord Length Formula. This formula states that the chord length is equal to 2 times the radius times sin (theta/2). Theta is equal to 1/2 of the central angle, and can be found by taking two points on either side of the curve and finding their angle w...
With all that in mind, the formula for calculating any circle's circumference is the length of the diameter chord length times π (Dπ). You may also see this expressed as two times the radius times π (2rπ), but the result will be the exactly the same using either version of the ...

To calculate arc length without the angle, you need the radius and the sector area: Multiply the area by 2. Then divide the result by the radius squared (make sure that the units are the same) to get the central angle in radians. Or you can use the radius and chord length: Divide ...
We derived a formula to compare the chord length and scleral arc length, when using calipers to measure the distance for suture placement, during retinal reattachment surgery. The scleral arc length is slightly longer than the chord length (caliper setting). The difference is 0.16 mm (2.0%) fo...
Find Arc Length using the Radius and Chord Length If you know the radius and chord length, but you don’t know the central angle, then you need to find the central angle first in order to use the formula above. Given this information, you can find the central angle of a sector with ...

We know that a circle is a very important two-dimensional shape in geometry. There is a term “arc” is used with reference to the circle. In this article, we will see the details about the arc and computation of the arc length formula with examples. Let
