Question

question 10 of 10 which best describes how to find the length of an arc in a circle? a. divide the arcs degree measure by 180°, then multiply by the radius of the circle. b. divide the arcs degree measure by 360°, then multiply by the circumference of the circle. c. divide the arcs degree measure by 180°, then multiply by the circumference of the circle. d. divide the arcs degree measure by 360°, then multiply by the radius of the circle.

Explanation:

The length of an arc is a fraction of the circle's circumference. The fraction is determined by the ratio of the arc's degree - measure to the total degrees in a circle ($360^{\circ}$). So, we first find this fraction by dividing the arc's degree - measure by $360^{\circ}$, and then multiply by the circumference of the circle.

Answer:

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