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

If you draw line through the center of the circle, to its edges, that can be called its ...

• Radius

• Diameter

• Circumference

 $Circumference\ =\ 2\ π\ r$  

• Yes, two times Radius multiplied by π

• No, two times Diameter multiplied by π

 $C\ =\ π\ D,\ then\ we\ can\ replace\ D\ with\ 2r$  

• Yes, because Diameter is 2r

• No, Diameter is not 2r
