The measure of the central angle of a circle is 45⁰
<h3>What is Angle?</h3>
A figure which is formed by two rays or lines that shares a common endpoint is called an angle.
Here, 
Theta (angle) θ = arc length / radius
θ = 15 π / 60 cm
θ =  0.79 radians
Convert to degrees
θ = 0.79 radians = 0.79 X 180/ π
                      = 0.79 X 180/ 3.14
                      = 45⁰
Thus, the measure of the central angle of a circle is 45⁰.
