The arc length between each car is 18.84 ft
How to get the length of an arc?
For a section defined by an angle θ in a circle of radius R, the length of the arc is given by:
A = θ*R
A complete circle has an angle of 2π. Now, if the circle has 25 cars, then it has 25 sections, so the angle that defines each one of these sections is:
θ = (2π/25)
And the diameter of the circle is 150ft, so the radius (half of that) is:
R = (150ft)/2 = 75 ft
Then the length of the arc:
L = (2π/25)*75 ft = 18.84 ft
