The CD's circumference is 15.7 inches.
I sense you're talking about the infinite disk, the hyperbolic disk or the Poincare disk. The limit of the circumference is infinite and a real number and is not actually part of the hyperbolic plane.

Multiply the radius by 2 x pi.
12 cm approx I'm a little surprised that you haven't got a CD and some sort of ruler or measuring tape near you. The idea of a homework question like that is to help you get some idea of common sizes.

A compact disk is an average CD.
A compact disk is an average CD.
The motor in a CD player (or any "disk medium" player) is necessary to spin the CD at a speed that the laser pickup can "read" the data on the disk. As the laser pickup moves along the surface scanning the disk, it causes the motor to slow down as it gets further out on the disk so the data is still read at the correct speed. Or just the opposite, reading from the outside egde of the CD the laser needs to read constitantly so the disk motor speeds up for the smaller circumference of the data on the disk. A combination of elecltronics monitors the motor speed, the data being read and the location of the laser computing the time necessary.
CD = Compact Disk
compact disk
it is a CD(Compact Disk) and a DVD (Digital Video Disk)
