This formula uses 1 Constants, 2 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Radius of Circular Curve - (Measured in Meter) - Radius of Circular Curve is the radius of a circle whose part, say, arc is taken for consideration.
Degree of Curve - (Measured in Radian) - Degree of Curve can be described as the angle of the road curve.

STEP 1: Convert Input(s) to Base Unit

Degree of Curve: 60 Degree --> 1.0471975511964 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_c = 5729.578/(D*(180/pi)) --> 5729.578/(1.0471975511964*(180/pi))

Evaluating ... ...

R_c = 95.4929666666847

STEP 3: Convert Result to Output's Unit

95.4929666666847 Meter --> No Conversion Required

FINAL ANSWER

95.4929666666847 ≈ 95.49297 Meter <-- Radius of Circular Curve

(Calculation completed in 00.004 seconds)
