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))

What is cirference of a circle with a 1.5 radius?
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
How do you determine the circumference of a circle if you know the radius?
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
What is the formula to find circumference when you are given the radius?
To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi
What formula do you use to find the radius diameter and circumference of a circle?
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
What is the formula to find a circumference if the radius is 3 and the diameter is 6?
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.
What is the formula for the diameter or a circle?
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

What is the formula for the radius of a circle when you have the circumference?
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.
Formula for circumference?
For a circle: circumference = 2 x π x radius. As the diameter of a circle is 2 x radius: circumference = π x diameter.
What is formula for figuring diameter of a circle?
diameter = circumference / pi diameter = radius * 2
What is th formula for the circunference of a circle?
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.
The area of a circle is 16 pi?
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.

What is the formula for the circumfriss of a circle?
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).
