**Reiny**, Wednesday, April 16, 2008 at 11:00pmarc length is not measured in "radians", but rather in linear units

if the angle is 1 radian, then the arclength supported by that 1 radian is 1 radius..

arclength = (radius)*(angle in radians)

BTW, that is the definition of 1 radian angle, the central angle of a sector with radius r and arclength of r.
