The distance from the outside edge of the CD to the inside edge is; 6.0 - 0.75 = 5.25cm.

<h3>Circumference, diameter and radius</h3>

Since the circumference of the CD is about 37.7cm

We can determine the radius of the CD as follows;

Circumference, C = 37.7 = 2 π × r.

However, the diameter of the hole in the center is; 1.5cm, therefore, the radius of the hole in the center is; 1.5/2 = 0.75cm.

Ultimately, the distance from the outside edge of the CD to the inside edge is; 6.0 - 0.75 = 5.25cm.
