Standard CDs have a diameter of 120 mm; that would be a radius of 60 mm. Since area is calculated as the value of pi (3.1416) times the square of the radius, we calculate as follows: Area A = pi X r2 = 3.1416 X 60 mm X 60 mm = 3.1416 X 3600 mm2 = 11,309.76 mm2. That value translates to 113.0976 square centimeters or 17.5301631 square inches. The area just calculated includes the hole. If you wish the hole excluded, so you have just the surface area of the disk, subtract the area of the hole, which has a diameter of 15 mm. The hole, with a radius of 7.5 mm, has an area of 176.715 mm2. Subtracting that from the area of a circle with a 120 mm diameter (11,309.76 mm2), we get a true surface area of 11,133.045 mm2 or 17.2562543 in2.
The diameter of a CD is 11.43 so the radius is 5.715.

According to Red Book specifications, a standard CD is 120 mm (4.75 inches) in diameter and 1.2 mm (0.05 inches) thick
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 disk is 12 cm, the size of a CD Box would have to be bigger to fit the standard size, but there are so many different styles of CD Boxes to give a correct measurement here.
a CD is 120mm (4.7 inches) in diameter and 60mm radius, the hole is 15mm diamter (0.6 inches).
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
a CD is 120mm (4.7 inches) in diameter and 60mm radius, the hole is 15mm diamter (0.6 inches).
The width of a standard CD (Compact Disc) is 120 millimeters (12 centimeters or about 4.7 inches). This diameter is consistent across most CDs, including audio CDs, CD-ROMs, and other types of compact discs. The thickness of a CD is approximately 1.2 millimeters.
Standard CDs have a diameter of 120 mm
The standard thickness of a CD is 1.2mm (about .05 inches), but can vary from 1.1 to 1.5mm.

A standard CD cover, also known as a CD jacket, typically measures 4.75 inches by 4.75 inches (approximately 12 cm by 12 cm) when folded. This includes the front cover, back cover, and spine. The artwork is usually printed on a square piece of paper that fits into a standard CD case, which is 5.6 inches by 4.9 inches (14.22 cm by 12.4 cm) overall.
