The diameter of the hole in the center of a standard compact disc (CD) is approximately 15 millimeters, which is about 0.59 inches in imperial units. This central hole allows the CD to be mounted on a spindle during playback.
A standard CD:- 15mm Internal diameter, 120mm external diameter, 1.1 mm thick A mini CD:- 15mm Internal diameter, 80mm external diameter, 1.1 mm thick

4.25 inches
the answer is 20
L=L(initial)[1+C(al)]*T =1.184cm I can't figure out the second one either
CD's have a diameter of 5.5 centimeters;)
15 mm
a CD is 120mm (4.7 inches) in diameter and 60mm radius, the hole is 15mm diamter (0.6 inches).
The hole in a standard CD is approximately the same diameter as a quarter, which is 24.26 mm. While the hole itself technically does not directly correlate to any specific coin, a quarter is a close match in size.
a CD is 120mm (4.7 inches) in diameter and 60mm radius, the hole is 15mm diamter (0.6 inches).

A standard CD is 4.75 5 inches rounded in diameter.

The hole in the CD is where the machine you put it in "grips" the CD so the disk can be spun and thus read and used.
