The formula given is schools is circumfrence=2(pi)radius. But since I am a rebel, I use diameter times pi. This works since diameter equals 2 times radius. If you don't know, pi exactly equals 22 divided by 7. Or 3.14159.....as for an example, if you have a circle with diameter of 2, then you plug it in the formula. Then get your answer or 2(pi).

How do you use the diameter to find the circumference of a circle?
Multiplying the diameter by pi (approx 3.1416) will give you the circumference of the circle.
How do you find out the the diameter of a circle if knowing the circumference?
Divide the circumference by the value of Pi - that will give you the diameter.
How do you find the area of a circle if you only know its circumference?
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
How do you find the radius of you know the circumfrerence?
Divide the circumference by 2*pi will give the radius of the circle.
Can you give me a sentence for the word circumference?
The circumference of a circle is the length around it.
