Hope someone will have some very good advice for me here. Let me see if I got you right (take a look at the attached picture): - you have the circle plate (green color) with a radius (white) - you want to make the strip (yellow part) and need the length of it If that is all you can calculate: length of strip: l radius of circle plate: r pi is a mathematical constant: 3.141592653... (If you don't know the number there is an easy way to calculate: take the numbers 1 3 5, double them 113355 and then divide 355 by 113 resulting in 3.141592920353982301 which is very close to pi)
Then the formula is: l = 2 * r * PI
Hope this helps
Best regards, Wolfgang
PS: I found a very good article about the number pi on
wikipedia (http://en.wikipedia.org/wiki/Pi)
