The diagram below shows circle with radii OA and OB. The measure of angle AOB is 120°, and
the length of a radius is 6 inches.
Which expression represents the length of arc AB,
in inches?

Length of arc AB = 4π

Step-by-step explanation:

Formula to get the arc length is given by,

Length of arc =

Here, θ = central angle subtended by the arc AB

r = Radius of the circle

By substituting the values in the formula,

Therefore, length of arc AB =

                                              = 40π
