Chord Length of Circle given Diameter and Central Angle Calculator

Calculate Chord Length





Formula

The formula to calculate the Chord Length of Circle is:

\[ lc = D \cdot \sin\left(\frac{\angle Central}{2}\right) \]

Definition

Chord Length of Circle is the length of a line segment connecting any two points on the circumference of a Circle. Diameter of Circle is the length of the chord passing through the center of the Circle. Central Angle of Circle is an angle whose apex (vertex) is the centre O of a Circle and whose legs (sides) are radii intersecting the circle in two distinct points.

Example Calculation

Let's assume the following values:

Using the formula:

\[ lc = 10 \cdot \sin\left(\frac{2.9670597283898}{2}\right) = 9.96194698091721 \]

The Chord Length is 9.96194698091721 Meters.
