The circumference of a circle is 2 pi r, where r is the radius, or it is pi d, where d is the diameter.there is no circuference of pi. Circumference refers to the outer edges of circles
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
C=2(pi)r
Diameter = Circumference/pi
Circumference = diameter(pi) so divide the circumference by pi to get the diameter.
