the circumference of a circle is pi time the diameter
Because:- circumference/diameter = pi and when the formula is rearranged circumference = pi*diameter
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
use the formula pi*diameter = circumference and the formula diameter = 2*radius and combine them 2pi*radius = circumference now you have a formula that you can just plug you numbers into. if you have 3 as your radius, then this is how to find the circumference 2pi*3=circumference 6.28*3=circumference 18.84=circumference
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter
They both are a formula
Formula: diameter = pi / circumference
Formula of Circumference of a circle: 3.14*Diameter of the circle. You could also do: 3.14*3.14*radius.
Area = (Circumference)2/(4*pi)
the formula is: circumference= p*diameter
circumference = pi multiplied by the diameter
to find the circumference of a circle you do 2 times3.14timesthe radius
