1 Radian Measure of a Circle another way to measure angles!

2 Opener: What is the circumference of a tire with a radius of 18”? How many complete revolutions does the tire make over 1000 feet?

3 What is a radian????

5 How to convert from …

6 Convert 235 degrees to radians: 235°{————}= radians

7

8 State your answer in terms of π! If you walk around a circular track with a radius of 100m a total of eight times, how many radians will you have traveled? What if the radius of the track were 1000m instead of 100m?
