Hi Chandra, I think that it is necessary find the angle theta, because the arc length depends on that. When I said radio I wanted to said ratio or dadius of circumference. bye. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google

Hi everybody. thanks for reply. Clarification: 1. When I said radio I wanted to said ratio of circumference. (sorry) 2. I am not solve the problem for this specific picture, I try to solve for any picture. Chandra could you explain me why L = k*C? I can see it. thanks again and happy new year f

If you can scan pixels, why not just count # of pixels in the arc and multiply by size of each pixel? finding line intersection seems like a hard thing especially on a scanned image like this one. oh wait minute, it's an image... do you mean you want to find the ratio of arc to circumference?

Hi, I assume radio or circumference as ratio of circumference and take that as L / C = k , where k is the ratio of circumferece and C is the circumference If so then C = 2 * PI * r L = k * C = k * 2 * PI * r But I'm not sure that my assumption is right or i
