"ARC" [space or enter] then "S" [space or enter]
Now pick or put in the coordinates of the Start point and press space or enter.
Now type "E" [space or enter]
Now pick or put in the coordinates of the End point and press space or enter.
Now type "R" [space or enter]
Now type in the radius and press space or enter.
That should do it !!
RE: Drawing Arcs.
You cannot unless you can eyeball the arc length
with microscopic accuracy. Why make it so hard when
you can easily get the angle of the arc knowing the
radius & arc length. Sometimes, software problem comes
up due to whimsical attitude & plain ignorance.
RE: Drawing Arcs.
1) Draw your arc using Start, End and Centre ensuring that you "overshoot" the arc length required.
2) Check the properties of the arc to determine the actual length drawn.
3) Draw a line from the end of the arc that is long enough to make the total combined length of the arc and line exactly double the required arc length.
4) Combine the arc and line in a Pline
5) Use the DIVIDE command to divide the Pline in 2.
6) Trim the arc off at the point created by the DIVIDE command.
Its not pretty, but it will work

P.S.
"Sometimes, software problem comes up due to whimsical attitude & plain ignorance."
Estassoc, was that really necessary?

2r*Pi= Circumfrence
Circumfrence/360=inches per degree
Length of required arc/inches per degree = degree of arc
So: Pick arc, then c or center, then pick center, then pick the start point or enter it as a relative cooridinate (@108,0), then enter A or angle to specify the angle, then enter the calculated angle (25.464791 deg).
I hope I made sense here.
