2*pi*radius of the circle
or
diameter*pi where pi = 3.1416 or 22/7
and is usually rounded to 3.14.
Well, the equation for finding the circumfrence of a circle is (diameter)(pi). That is diameter times pi. since the diameter of a circle is 2 radii, we can say that there is 2(pi) radii in a circle.
The 3 times circle rule is a rule for finding the circumfrence of a circle. Basiclly, you multiply the diameter by 3.

The circumference of a circle is (diameter) multiplied by (pi).
the radius squared x pi

The 3 times circle rule is a rule for finding the circumfrence of a circle. Basiclly, you multiply the diameter by 3.
The circumference of a circle can be found using the equation c=2πr. For example, if a circle has a radius of 10, its circumference is 20π, or 62.832.

Circumfrence
the circumfrence of a circle is pi times it's radius squared.

Circumfrence is the perimeter of a circle, the line that makes a circle looks like a circle Imagine a perfect circle drawn on a piece of paper. Take the length of the line of the circle (by line I mean the part that is actually drawn on the piece of paper the ring) and there, you have the circumfrence. The circumfrence is exactly π times the size of the diameter (if you don't know what those two things are ignore this)
