what is the length of the inscribed arc when the radius is four and the gien arc is 120 degrees?

OpenStudy (mathmale):

the formula for "arc length" is \(s=r*theta\), where r=radius and theta is the central angle.

OpenStudy (mathmale):

@ParthKohli has reminded me that that central angle MUST be in radians. So, please convert 120 degrees to radians.
