Hi,
Given parameters are:-
Slope arc length
Angle on Slope
Arc radius
Is there any way to calculate flat arc length?
Thanks!

What do you mean by 'flat' arc length? Were you meaning to list some data?
Arc length is given by s=r{\theta}.
Where r is the radius of the circle and {\theta} is the central angle.
Where \theta is in radians.
Of course, s is the arc length.
For instance, suppose you had a radius of 1000 feet and a central angle of \frac{\pi}{6} radians (which is equal to 30 degrees).
Then, the arc length is s=1000(\frac{\pi}{6})=\frac{500\pi}{3}=523.6 \;\ feet
There is also a more complicated formula using calculus. I can give you that if you wish.
If this is not what you meant, please be more specific with an example.
