circumference=r2pi
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
Area = (Circumference)2/(4*pi)
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
The formula for circumference is pi*d = circumference. Therefore just divide the circumference by pi to get diameter. Approx. answer = 5.73
circumference=r2pi
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
The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius of the circle.
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.
the formula is: circumference= p*diameter
Area = (Circumference)2/(4*pi)
the circumference of a circle is pi time the diameter
