circumference dimension

Can you dimension the circumference of a circle or dimension the length of and arc? I know list will give you the circumf, but I want to actually Dimension the circle right on the drawing. Can this be done? Thanks in Advance

 

perhaps this is a stupid question? My co-worker asked me that, I know a lot about CAD but have never saw the use in being able to do this,...but it got me curious...I guess my curiosity has now embarrassed me.... darn.

 

Working in Surveying I routinely label curves with Radius, Length, Delta
(Central Angle) and sometimes a Chord Bearing and Distance. This is
necessary to properly describe the arc. Especially if it is not tangent to
other lines or curves.

My company bends pipe and tubing. By knowing the arc length, I can determine the approximate length for ordering material. The material does stretch during bending on most machines, and trimming is required. Some
bending machines have a boost arm that actually causes the tubing to shrink length wise while bending.
