A circular curve has a 200m radius and 60 deflection angle. What is it...
Given:
Radius of the circular curve (R) = 200 m
Deflection angle (θ) = 60 degrees

Formula:
The length of a circular curve can be calculated using the formula:

Length of Curve (L) = (θ/360) × 2πR

Calculation:
Substituting the given values into the formula:

L = (60/360) × 2π × 200
L = (1/6) × π × 200
L = (1/6) × 3.1416 × 200
L = 0.5236 × 200
L = 104.72 m

Therefore, the length of the curve is 104.72 m.

Answer:
The correct answer is option A) 209.33 m.

Length of the curve is given by,

The tangent length of the curve is given by,

Where,
Δ = Deviation or deflection angle in degrees
Δ = 180° - Angle of intersection
R = Radius of the curve in m
Given,
R = 200 m, Δ = 60°
