The circumference of a circle = pi*diametre = 2pi*radius
Pi times the diameter of a circle gives its circumference.
Circumfrences are only for circles.
Circumference of any circle = 2*pi*radius or pi*diameter
to calculate circumference you find a circles radius or diameter. you do diameter times pi or radius times 2 times pi. the you have circumference!
circumference is only in a circle. Circumference only applies to circles, ellipses, or other round objects. If you want to find the "perimeter," add up all three sides.
Divide by pi and then divide by 2
circumference = 2*pi*radius or pi*diameter
An arc
It is 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.
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
