Question

Consider the following measures shown in the diagram with the circle centered at Point A. Determine the approximate arc length of overline CB . Find the length of the are intercepted by a central angle of /and a radius of inches.)

Answer 1

Arc Length = 2πr (a/360)

Where:

r= radius = 4 in

a = angle = 110°

Replacing:

Arc Length = 2* π* 4 (110/360)

Arc Length = 8 *π ( 0.3055555)

Arc length = 25.13 ( 0.3055555)

Arc length = 7.68 in (option b)
