question 1 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 circumference by 360°.
d. divide the measure of the arc by 360°.

Explanation:

A full circle has a total angle measure of 360°. The fraction of the circle an arc covers depends on the arc's central angle relative to this total. Dividing the arc's measure by 360° gives this fraction.

Answer:

D. Divide the measure of the arc by 360°
