In the previous section you designed and explored wheels in Tinkercad. These wheels may look like a perfect circle, but they are not. The edges are made up of small line segments. You can see this better if you use the Tire shape in Tinkercad. Here are some shapes made with the Tires shape to help you explore math about circles.
If you can print out this page:
- Draw a more perfect circle around the edge of each tire. Use your pencil and string.
- Draw lines on each circle to show the radius and the diameter.
