The length - L - of a chord when dividing a circumference of a circle into equal number of segments can be calculated from the table below. The chord length - L - in the table is for a "unit circle" with radius = 1.
To calculate the actual length of a chord - multiply the "unit circle" length - L - with the radius for the the actual circle.
A circle with radius 3 m is divided in 24 segments. From the table below: the length - L - of a single chord in a "unit circle" with 24 segments is 0.2611 units.
The length of the chord for a circle with radius 3 m can be calculated as
0.2611 (3 m) = 0.7833 m
The summarized length of all chords in the circle can be calculated as
(0.7833 m) 24
= 6.2653 (3m)
= 18.7959 m
The circumference of the circle can be calculated as
C = 2 π r
= 2 π (3 m)
= 18.8496 m
