On a Chord Length to Arc Length Ratio for Closed Curves Undergoing a Length-Rescaled Curvature Flow Erik Forseth July 13, 2007 We use the same notation as in the proof of the theorem for open curves. However, now we are going to want to define a new quantity since l is not smoothly ...
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...
Arc length refers to the parametric curvilinear length between the two ends of the stent along the axis, whereas the chord length refers to the direct straight distance in 3D between the two ends of the stent. From:Handbook of Vascular Motion,2019 ...

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 ...
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 can clearly see in the screenshot above that the calculator provides us with not just the values of the arc length, but also gives us the sector area, the length of the chord as well as the length of the diameter. All the associated calculations are provided for reference and understan...
