question 3 of 10
how would you find the fraction of a circle that an arc covers?
a. divide the diameter by 360°
b. divide the measure of the arc by 180°.
c. divide the measure of the arc by 360°.
d. divide the circumference by 360°.

Explanation:

Step1: Recall circle - arc relationship

A full - circle has 360°.

Step2: Determine the fraction

The fraction of a circle that an arc covers is given by the ratio of the measure of the arc to the measure of a full - circle (360°). So we divide the measure of the arc by 360°.

Answer:

C. Divide the measure of the arc by 360°
