Radius to Circumference
Which Point is at the Center of the Circle?
Make sure point A is on 0. Move point B to 2 on the x axis.
What part of the circle is line segment AB?
What is the measure of the Radius when point B is on 2?
Keep point A on 0. Move point B to 4 on the x axis.
What happens when you move point B from 2 to 4?
When you move point B from 2 to 4, what happens to the length of the radius?
As the length of the radius gets larger, the size of the circle ___________________
