Because it must hold all of Beethoven's 9th symphony.
It is the same like a normal CD. It's 12 cm, or 120 mm.
Tall? My CD's are round with a diameter of 120mm and 1mm thick.
During operation, a typical cd drive will draw 150 milliAmps while playing and about 600 milliAmps during writing. cd drives are attached to the PSU via a 12 volt rail, so this equates to 1.8 to 7.2 watts.
If the CD is a CD-R it is only "Writable," and cannot have songs added to it after its initial burn. If the CD is a CD-RW you should be able to "Rewrite" songs onto the CD and reburn them.

CD's have a diameter of 5.5 centimeters;)
It is the same like a normal CD. It's 12 cm, or 120 mm.
A cylindrical paint can has a diameter of 12 centimeters and a height of 16 centimeters. Which isclosestto the volume of the paint can in cubic centimeters?
113.1 square centimeters.
A circumference of 37.7 centimeters.
According to Red Book specifications, a standard CD is 120 mm (4.75 inches) in diameter and 1.2 mm (0.05 inches) thick
If the diameter is 12 cm the radius is 6 cm.
The volume is about 1231.5 cube centimetres.
It is: diameter/2 = 6 cm
A circumference of 37.7 centimeters.
To convert from cm to inches, divide by 2.54.
the area of a circle is pi times the radius squared. The diameter is 12, so the radius is 6 (half of the diameter). Therefore, the area is pi times 6 squared, which is 36 pi square centimeters. Also, if you want the answer in decimal, it's 113.09733552923255658465516179806 square centimeters.
