question 2 of 10
which best describes how to find the length of an arc in a circle?

a. divide the arcs degree measure by 360°, then multiply by the circumference of the circle.

b. multiply the arcs degree measure by 360°, then divide by the radius of the circle.

c. multiply the arcs degree measure by 360°, then divide by the circumference of the circle.

d. divide the arcs degree measure by 360°, then multiply by the radius of the circle.

Explanation:

The arc length is a fraction of the circle's circumference. The fraction is the arc's degree measure divided by 360° (total degrees in a circle). Multiplying this fraction by the circumference gives the arc length.

Answer:

A. Divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
