Circumference and Area of Circles

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.
