    You see that 15 number on that segment? That is a radius, in which, that number times two. Which equals 30, then you take 30 times pie to find the circumference. Then you take 94.25 times the arc measure (60 degrees) divided by 360 degrees. The arc length for this arc is 15.7. What about the other arc? Well, just take 360 - 15.7 and you will get the other arc length. All arc lengths added up equal to 360, as well as the Arc measures.

    Finding Arc Measure
    To find the Arc Measure you will need to use the Arc length equation. Instead the Arc measure is a variable. Like this: Arc Length= X/360 x Circumference. So, lets say your arc measure is 75 degrees:
