L = 2Rsin(θ/2).
Where
L= length of chord.
R= Radius of curve.
θ = Degree of curvature.
Where
L= length of chord.
R= Radius of curve.
θ = Degree of curvature.

The degree of the curve is 5.73 degrees.
The formula for the degree of a curve is:
Code snippet;
Degree = 1720/R.
Use code with caution. Learn more
Where R is the radius of the curve.
In this case, R = 300 m, so the degree of the curve is:

Degree = 1720/300 = 5.73 degrees.

@All.
Someone are directly using 1719 or 1718 but this will only work if length of chord is 30 m so use basic formula c = r sin (d/2).

1720/D.
= 1720/300 = 5.73.
= 1720/300 = 5.73.

R=1719/D or; D=1719/R,or D=1719/300=5.73°.

Chord length formulae:
r = c / 2 sin (Dc/2).
Above formulae after values substitution answer will come.
sin (Dc) = 5.73°.
r = c / 2 sin (Dc/2).
Above formulae after values substitution answer will come.
sin (Dc) = 5.73°.

r=180 A/π * Dc.
Another formula for arc or chord length.

Thanks for the answer.

R =1719/D is correct because we can say that the length of chord or length of arc is 30 m and finally we get D=5.73
