How to find arc length

[Anonymous]

Hi,

Im struggling to find 2 lengths of an arc. See attached.

I have tried so many things now to find it, but now i will ask here to get the problem solved.

I need 2 lenghts for the arc, before the pipe is bent and when it is bent ( like you see in attached drawing)

Can someone show me how to find these 2 lenghts for the arc ?

Some really good guy from this forum,helped me with the attached drawing.

Hope there is one more to help me with this 🙂

When I post an .ipt file you will see less than in the video what to do.

What do you not understand in the video, where do you have problems (and which problems) to follow the shown steps?
