Angles, PI, Inconsistent Units

I'm trying to find the volume of sweeping a triangle along an arc. Simple math, not so simple in Revit for me.

I need to get the length of the arc to multiply by the area of the triangle (which I have).

I'm having a number of issues. 

  • Getting the Angle of the arc to Radians
  • Using PI in a formula
  • Inconsistent units

I'm stumped on putting the variables together in my Parameters so they report the volume for me.

Right now, I just need L for the Arc Length.  

Length = (Radius * Angle in radians)

It's getting the Angle in Radians that is stumping me. Can someone give me a clue? Even then, I'll probably get the Inconsistent Units warning.

Got it figured out. It comes down to units. I ended up making new variables as 'numbers' instead of 'length', 'area', 'volume' etc. Then when doing calculations I made sure to cancel out the units by multiplying or dividing by 1' or by 1 rad (for 1 radian). I love Revit, but really hate this unit policing we must do.

Ah! That answers the pi thing. Thanks, as it was still stumping me.
