By knowing the properties of circles, the circle with a central angle ACB of 48° and the arc length AB is 144 inches has a circumference of 1080 inches.
How to determine the circumference
According to the Euclidean geometry, the circular arc (s), in inches, is directly proportional to the central angle (θ), in radians:
s = θ · r (1)
Where r is the radius of the circle, in inches. Please notice that the arc is directly proportional to the central angle and that the circumference is determined for a central angle of 360° (2π). Hence, we can determine the circumference of the circle by using the following relationship:
s/144 in = 360°/48°
s = (144 in) · (360°/48°)
s = 1080 in
