Question

a circle has a radius of 20 centimeters and a central angle that measures 216 degrees find the length of the arc defined by this central angle

Answer 1

24π cm.

or

75.40 cm to the nearest hundredth

Explanation:

The circumference = 2 π r = 2 * π *20

= 40π cm.

Length of the arc = 40 π * 216/360

= 40 * 0.6 * π

= 24π cm
