Final answer:
The length of the diameter BC is 4 cm. The measure of the small arc AC can be calculated using the formula: arc length = (measure of angle / 360) * circumference.
Step-by-step explanation:
The length of the diameter BC can be calculated using the formula:
BC = 2 * radius
Given that the radius of the circle is 2 cm, the length of the diameter is:
BC = 2 * 2 cm = 4 cm
The measure of the small arc AC can be calculated using the formula:
arc length = (measure of angle / 360) * circumference
Given that the measure of the angle BAO is 60° and the circumference of the circle is 2π * radius (2π * 2 cm), the measure of the arc AC is:
arc length = (60° / 360) * (2π * 2 cm)
