Arc= 2.pi.rAngle/360



14pi= 2.pi.18.Angle /360


Angle = 360.14.pi/2.18.pi


Angle = 140

Measure of the given central angle of arc is 140°

Central angle of an arc

Given that:

Measure of arc = 14π

Radius of circle = 18 unit

Find:

Measure of the central angle of arc

Computation:

Length of arc = [θ/360][2πr]

14π = [θ/360][2(π)(18)]

14 = [θ/360][36]

θ = 140°

Measure of the central angle of arc = 140°
