A radius is where a segment from the center to the circle.
A diameter is a segment passing through side to side through the center.
- The radius is going to be HALF of what the diameter is.

Radius is the length of the line segment from the center of the circle to an endpoint on the circle and diameter is twice the length of the radius of the circle.
