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 converse of the statement "If two circles have the same diameter, then they have the same circumference" is "If two circles have the same circumference, then they have the same diameter." This means that if you know two circles share identical circumferences, you can conclude that their diameters are also equal.
The circumference of a circle = pi*diametre = 2pi*radius
The equator.
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)
Then they are similar.
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
Yes.
