1. A circular track has three lanes, each of which is 5m wide. The inner perimeter of the inner-most lane is 100m. What is the outer perimeter of the outer-most lane?
2. A circular track (1 lane) is divided into 11 sections of identical size and shape. The inner arc of one section is 18 inches long. The outer arc of one section is 25 inches long. How wide is the track?
We will do these in class, so the video is provided here for reference as needed. A few examples of solving questions utilizing radian measure and the s = rθ formula.
