The circumference of a circle can be found by multiplying pi ¶ (which is equal to 3.14) by the diameter of the circle.
If a circle has a diameter of 4, its circumference is 3.14*4=12.56
If you know the radius, the diameter is twice as large.

radius x pi (3.14) x 2 if the radius is given diameter x pi (3.14) if the diameter is given

pi=3.14
C=pi*diameter
OR
C=pi*radius*2

2Ïr, which is
2 times pi times r
pi, by the way, is about 3.14, and r is the radius of the circle
