The Chord of a Circle calculator computes the length of a chord
(d) on a circle based on the radius (r) of the circle and the angle of the arc (θ).
INSTRUCTIONS: Choose units and enter the following:
- (θ) The length of the arc
- (r) The radius of the circle
Chord of a Circle (L): The calculator compute the length of the chord (d) in meters. However, this can be automatically converted to other length units via the pull-down menu.
The Math
The formula for the length of a circle's chord from the radius and angle is:
where:
- L is the length of the chord
- r is the radius of the circle
- θ is the angle
