The Circumference of a circle is the distance around the outside of the circle.
The Radius is the length of a line from the Center out to the Edge and ...
The Diameter is the length of a line that passes through the Center from one Edge of the circle to the Edge on the opposite side.
circumference = 2*pi*radius or pi*diameter
It is an arc
An arc
The circumference of a circle = pi*diametre = 2pi*radius
The equator.
Then they are similar.
Pi times the diameter of a circle gives its circumference.
The ratio of the circumference of a circle to its diameter is Pi. (3.14159)
Circumference is a special name for a circles perimeter. I think the answer you are looking for is radious.
Any circle's circumference can be calculated with the formula 2(pi)*radius
Circumfrences are only for circles.
