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
I think my grandpaents dies to minutees
You do a diameter circle!!
It is half of the diameter or radius = diameter/2
The cord of a circle that contains the center of that circle is a diameter of that circle.
CD's have a diameter of 5.5 centimeters;)
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 standard CD is 4.75 5 inches rounded in diameter.
The diameter of a CD is 11.43 so the radius is 5.715.

Tall? My CD's are round with a diameter of 120mm and 1mm thick.
15 mm
The diameter of a CD is about 12 cm, so since the radius is 1/2 of the diameter, that would make the radius about 6 cm. 5.23 cm
The radius of a circle is the distance from the centre to the edge. The diameter is the distance right across the circle through the centre. So the diameter of a circle is always twice its radius. So if the radius of a circular CD is 6cm, the diameter is twice this - 12cm.
Close to 12cm
According to Red Book specifications, a standard CD is 120 mm (4.75 inches) in diameter and 1.2 mm (0.05 inches) thick
It is the same like a normal CD. It's 12 cm, or 120 mm.
