Question

What is the arc length for a central angle of 120° on a circle with radius 5 units?

Answer 1

Answer:

(10/3)π units

Step-by-step explanation:

120 degrees is equivalent to (2π)/3 radians.  Applying the arc length formula s = r Ф, we get:

s = arc length = (5 units)(2π)/3 = (10/3)π units
