Would this formula find the arc measurement in degrees or radians?

Actually... if you have the arc measurement and use this formula to find the central angle, would the initial answer (after plugging everything in) have the central angle in DEGREES or RADIANS?

for the arc of a circle ... . yes
subtended at an angle = central ange
mArc = (Central angle/360) x 2(pi)(r)

you have the central angle in degrees and by the division you are transforming it into radians .
If the central angle is in rad no need to divide by 360-
The arc is given in units of length ( the same as r)
