Radius is the distance from the outside of the circle to the center.
Diameter is the distance ACROSS the circle, it's formula is:
D = 2R (Diameter is 2 times the Radius)
Circumference is the distance AROUND the circle.
C = Pi D, where Pi is the constant 3.1415.... (look it up))
the formula for the circumference of a circle is pi*diameter. the diameter is 2*radius so if 1.5 is the radius, 3 is the diameter plug 3 into the formula... circumference=3.14*3 circumference=9.42
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
To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi
Radius is diameter divided by two. Diameter is radius times two or circumference divided by pi. Circumference is diameter times pi. Pi is roughly 3.14
The circumference of a circle is given by the formula C = 2πr where r is the radius. But, as the diameter is 2 x radius then the formula can be written C = πd where d is the diameter. In this example the circumference = 2π3 = 6π = 18.85 units.
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

well the circumference is equal to pi times the diameter, so all that you have to do is divide the circumference by pi to get the diameter. Then you divide the diameter by two to get the radius.
For a circle: circumference = 2 x π x radius. As the diameter of a circle is 2 x radius: circumference = π x diameter.
diameter = circumference / pi diameter = radius * 2
π is the ratio between the diameter and the circumference of a circle so the formula would be : Circumference = π x Diameter or alternatively (since the radius is half the diameter) Circumference = 2π x Radius.
And what is the question? Please always state your question on this site.If you need the radius, the diameter, or the circumference, use the formula A = pi x r2 to calculate the radius. The diameter is twice the radius; the circumference is radius x 2 x pi.And what is the question?

It is called circumference. This is usually calculated from the diameter (circumference = pi x diameter), or from the radius (circumference = 2 x pi x radius).
