Relationships between a circle's diameter and circumference M2D-21a
The purpose of this applet is to allow the user to change the size of a circle's diameter and look for a relationship between the length of any circle's diameter and its circumference. Drag Point B to different places and record your findings.
Answer the following questions on your notes page:
1. How can you calculate the circumference when you know the diameter?
2. How can you calculate the circumference when you know the radius?
3. If you know the circumference, how can you calculate the diameter or radius?
