Question

a circle has a radius of 4.5 inches find the length of the arc outlined by a central angle that measures 0.6pi radians

Answer 1

8.478in

Explanation:

Length of an arc = rtheta

r is the radius of the circle = 4.5in

theta is the central angle = 0.6pi

Substitute

Length of the arc = 4.5 * 0.6pi

Length of the arc = 4.5 * 0.6 * 3.14

Length of the arc = 8.478inches

Hence the length of the arc is 8.478inches
