Question

I need help with this thanks!!!!!

Answer 1

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

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.
