Can't remember how to calculate an ARC LENGTH in C/K99

Can't remember how to calculate an ARC LENGTH in C/K99

Can't remember how to calculate an ARC LENGTH in C/K99

(OP)
I am trying to remember how to use C/K99 to calculate the distance between two points on a circle.  The circle is Ø1.16250" and the circumference is 3.625".  The two points are located 129.611° apart from each other, so how do I do this and what IS the arc length between the two points?  Thank you!

RE: Can't remember how to calculate an ARC LENGTH in C/K99

129.611/360 x 3.625 = ARC LENGTH
Verify, Distance, 2 Points is the easiest method for the distance measurement.

Thank you! Thank you!! This is the second time you have helped me jog my memory.  I don't feel like I am 76 years old, but my memory continues to let me know. I'm quite sure that this is the primary reason I don't upgrade to K/C...just too much of the old dog and new tricks. I DID, however try the VERIFY DISTANCE BETWEEN 2 POINTS, and it kept giving me the chord measurement, which I didn't need, and I didn't remember how to get it to understand what I wanted.

Thank you, again for such a rapid response!! Warmest wishes!

Data, Verify, Perimeter will also give the length as long as the actual arc is separate from the rest of the circle.

It's a GOOD DAY!!

One thing should be pointed out is that 3.625 is not the circumference of a 1.1625 dia. circle, it's 3.652.  May be a typo.

Hey, old friend!  Yes, it was a typo, but when I realized it, it was too late to edit.  Thank you for the sharp eye!!  Good to hear from you, and THANK YOU for catching that!  I could have put the wrong dimension in if I hadn't caught it.

Best wishes!
