Question

a circle has an arc of length 48pi that is intercepted by a central angle of 120°. what is the radius of the circle?

Answer 1

Answer:

60 degree

Step-by-step explanation:

Answer 2

Answer:

72 units.

Step-by-step explanation:

arc length = r * C  where r = radius and C is the angle in radians, so

48pi = r * (120 * pi / 180)

48 = 120r/180

120r = 48* 180

r =  48 * 180/120

r = 72 units.
