First, find how many inches around (circumference) is the
entire circle. Use formula C+=+2%2Api%2Ar
C+=+2%2A3.141%2A45
C+=+282.7 in
How long is the arc in inches?
1.667%2A12+=+20 in
Find ratio of arc to circumference
20+%2F+282.7+=+.0708
There are 360 degrees in a circle
arc in degrees / 360 = .0708
arc in degrees = .0708 * 360
.0708%2A360+=+25.47degees answer
