If the length of an arc is 12 pie inches and the radius of the circle is 10 inches, what is the measure of the arc?

Find circumference

C=2pir

c=2pi10

c=20pi

circle is 360 degrees

12pi/20pi=x/360

6/10=x/360

3/5=x/360

216=x

answer si 216 degrees

if yo want radians

3/5 was the fraction and 2pi is total so

3/5 times 2pi=6pi/5 radians

216 degrees or 6pi/5 radians
