Question

What is the measure (in radians) of central angle \thetaθtheta in the circle below?

Answer 1

Hello,

To solve this problem, we need the right formula, which is: s = (r)(theta) where “s” is the arc length
r = 2, s = 5 from the image
1. s = (r)(theta)
2. 5 = (2)(theta)
3. 5/2 = theta
4. theta = 2.5 radians

Good luck to you!
