1. Find the length of AB. Round it to the nearest hundredth.

Given that the radius of the circle is 6 cm.

The central angle is 120°

We need to determine the length of AB.

Length of AB:

The length of AB can be determined using the formula,

where is the central angle and r is the radius of the circle.

Substituting and in the above formula, we get;

Simplifying the values, we get;

Substituting π = 3.14, we have;

Thus, the arc length of AB is 12.56 cm
