Question

A circle with a radius of 6 m has an arc of 4 pi m. What is the measure of the centra angle?

Answer 1

Answer: Since the arc length is given (4 ) and the radius is given (6), the central angle can be found

Arc Length = theta * r

4 pi = theta * 6 Divide by 6

4 pi / 6 = theta

theta = (2/3) pi
