Question

the length of segment ac is centimeters.

Explanation:

Step1: Recall the definition of diameter and radius.

The line - segment BC is a diameter of the circle with center A. The radius of a circle is half of the diameter.

Step2: Determine the length of segment AC.

Since AC is a radius and the diameter is 12 cm, and \(r=\frac{d}{2}\), where \(d = 12\) cm. So \(AC=\frac{12}{2}=6\) cm.
