a circle has an arc of length 56 pie that is intercepted by a central angle of 120°.
what is the radius of the circle?

Therefore radius is 84 units.

Step-by-step explanation:

Given:

arc length = 56 pie

Central angle = θ = 120°

pi = 3.14

To Find:

Radius = r =?

Solution:

If the θ  measured in degree then the arc length is given as

Where r = radius, θ = Central angle

On substituting the values we get

Therefore radius is 84 units.
