Radius and Diameter from Circumference

The radius of a circle is

• The measurement from the center of a circle to an edge of the circle.

• The measurement around the circle

• The measurement from and edge of the circle to another edge through the center

• A line perpendicular to the diameter of the circle

The diameter of a circle is:

• The measurement around the circle.

• The distance from an edge of a circle to another edge.

• The distance from the center of the circle to an edge of a circle

• The distance from an edge of a circle to another edge through the center.
