Check my answer a central angle θ in a circle with a radius of 5.5 centimeters intercepts an arc with a length of 7.7 centimeters. what is the radian measure of θ ? enter your answer, as a decimal, in the box i used 80.2

First you need to find the Circumference
C = 2 pi r = 2 * 3.14 * 5.5 = 34.54

Arc measure / 360 = 7.7 / 34.54
Arc measure = 7.7 * 360 / 34.54
Arc measure = 80.25

80.25 if you are using pi = 3.14
80.2 if you are using pi = 3.141592

Answer a. you’re welcome
