Question

If the arc on a particular circle has an arc length of 14 inches, and the circumference of the circle is 84 inches, what is the angle measure of the arc?

60°
90°
120°
180°

Answer 1

the arc length is 14 and circumference is 84

so it is 14/84 of the circle. 14/84 can reduce to 1/6

a circle has 306 degrees

now multiply 360 x 1/6 = 60 degrees which is the angle measure
