--------
ID of the pipe = 2r
---

Solve for r.
ID = 2r
Subtract from 3.5

OD � = 3.5
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
7 x 12 = 84 inches long
449/84 = 5.35
ID (Internal Diameter): 2 x (5.35/Pi) = 3.4
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3.5 - 3.4 = 0.1; 0.1/2 = 0.05 inches is the wall thickness of the tube.
NOTE: This is a very thin tube, 0.05 is about the thickness of printing paper
