RADIUS The distance from the center to a point on the circle is the radius of the circle. All radii of a circle are congruent.
4
DIAMETER The distance across the circle, through its center, is the diameter of the circle.
5
The diameter is twice the radius.
6
Examples The diameter of a circle is 15cm. What is the measure of the radius? The radius of a circle is 6in. What is the measure of the diameter?
