Here is the equation from GATF's Handbook of Graphic Arts Equations:

Linear Feet of a Roll = 65.45 X [(Roll Diameter)2 - (Core Diameter)2]
                                                       Paper Caliper X 1,000

Note: The 2 means squared. My email software doesn't recognize superscripts.

The Handbook of Graphic Arts Equations also contains software that has these
formulas that can be put on your computer. Let me know if you need more
information.
