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
327mm ;)
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 small hole at the center of a CD is called the "spindle hole" or "hub hole." This hole allows the CD to be securely attached to the spindle of a CD player or drive so that it can be properly read and played.
A standard CD is 4.75 5 inches rounded in diameter.
The circumfrence of a compact disk is 37.6991118 cm or 37.70cm rounded or nearly 15 inches.

4.24563 inches is the diameter of a golf hole.
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.
The diameter of a CD is 11.43 so the radius is 5.715.
