In the diagram above, the radius of the circle is 20 units and the length of arc AB is 15(Pi) units. What is the
measure in degrees of angle AOB?
Correct Answer:
135
Explanation/Reference:
The length of an arc is equal to the circumference of the circle multiplied by the measure of the angle that
intercepts the arc divided by 360. The arc measures 15(Pi) units, the circumference of a circle is 2(Pi)
multiplied by the radius, and the radius of the circle is 20 units. If x represents the measure of angleAOB,
then:
The measure of angle AOB is 135 degrees.
