Answer 1

To find the length of an arc you first calculate the circumference of the entire circle (360 degrees). You can use pi x diameter to get this number.
You multiply this measurement by the fraction of the circle represented by the arc you want to measure, for instance,
for a 45 degree arc that is 45/360.
