Question

The radius of a circle is 5 centimeters. What is the angle measure of an arc 41 centimeters long? r=5 cm (=47 cm

Answer 1

Let the angle = A

Length of the arc is given by (A / 360) * 2 * pi * r, where A is the central and r is the radius

Therefore A / 360 * 2 * pi * r = 4 * pi

(A / 360) * 2 * 5 = 4

A = 4 * 360 / 10 = 144 degrees Option 4
