The arc length should first be compared to the circumference. This comparison will help establish the relationship that the arc length is proportional to the radius of the circle based on the angle subtended at the center.
To derive the fact that the length of the arc of a circle intercepted by an angle is proportional to the radius of the circle, what should the arc length first be compared to? (1 point)
• the circumference
• the area
