Question from Yoh:

Hello,

I am trying to find impressions on a roll (either full roll or partial).

Let's say I have the following information.

- Outer Diameter of roll

- Inner Diameter of roll (cardboard core)

- thickness per layer

- Each cut off length (impression length)

Now let's say a roll has a 40in outer diameter, the cardboard core has a 3.75in diameter and a thickness of .002. Each impression has a cut off of 14inches.

With this the roll will have approximately 2,700 impressions. How would I find the remaining impressions if the outer diameter of the roll is only 6.5inches?

Thank you.
