Question 1

What is a Chord Length Calculator?

Accepted Answer

A chord is a straight line segment connecting two points on a circle. The chord length calculator uses the radius and central angle to find both the chord length and the sagitta (the height of the arc above the chord).

Question 2

How does the Chord Length Calculator work?

Accepted Answer

Chord = 2r × sin(θ/2) Then: Sagitta = r × (1 − cos(θ/2)) Then: θ is the central angle in radians Then: Maximum chord is the diameter (θ = 180°).

Question 3

Can you give an example of how to use the Chord Length Calculator?

Accepted Answer

Example: Input r = 10, θ = 60° gives a result of Chord = 2×10×sin(30°) = 10.
