Ah, well it should matter mathematically. If the disk is spinning, the outer edge is moving faster than the inner portion. As a result, the outer edge is heavier and more compressed, and distorting space more. Consequently, the irrational number of pi no longer exists – well it’s no longer useful other than an estimate. I have no standing to engage in a math discussion with you (beyond simple addition) but I think I am right about this.
Ah, the classic difference between a scientist and the engineer. The scientist sits around trying to figure exact answers to questions which are meaningless. The engineer simply estimates the correct answer and then goes on to build the disc.

Actually, the effects of the manufacturing tolerances dwarfs (by many orders of magnitude) the nearly infitintesimal area modification caused by the outer stretching in a spinning CD. In fact, the Heisenberg Uncertainity Principle will tell you that the difference is likely not even measurable! Which means is matters not to the engineer, but only the scientist!
