If a radius of curvature of a simple curve is 229.2 m, then its degree of curvature is-

Correct option is A

The degree of curvature (D) of a curve is determined by the relationship:
D = 360 / (2πR)
Where: - R = Radius of curvature (in meters) - D = Degree of curvature (in degrees)
Given:
Radius of curvature, R = 229.2 m
Calculation:
Using the formula: D = 360 / (2π × R) D = 360 / (2 × 3.1416 × 229.2) D ≈ 360 / 1440.857 D ≈ 0.25 × 360 = 2°
