If you think on the lines of the neutral axis of the piece your cut length will come out close plus the flat material on the ends . When you bend something, the outside area is stretching and the inside area is compressing. When we bend and cut an arc we calculate the circumference of the web were we can wrap a tape ruler around and cut to size.
