Choose a radius for a circle. using a compass and a ruler, draw a circle with your chosen radius. now you are going to teach others how to draw a second circle with a diameter that is equal to the radius of your first circle.
a. create a video or an audio recording of yourself describing the process to other students, or write out the steps with illustrations. feel free to use effects in your video (e. g., speed up drawing).
b. your presentation should include a discussion of the relationship between radius and diameter.
