easy peasy remember that the arc is a part of the perimiter of the circle aka circumference also 360 degrees=circle
we are given the radius calculate circumference c=2pi times r r=14 c=pi times 2 itimes 14 c=28pi
100 degrees is the arc
find what fraction of the circumferece thei srepresents whole=360 100/360=10/36=5/18 so if circumference=28pi then multiply 5/18 by that 5/18 times 28pi=140pi/18=70pi/9 legnth=(70pi)/9 cm if you were to aprox pi to 3.14 then the answer would be 24.4222222 cm
