Pi represents the ratio of the circumference of a circle to its diameter. If you know the diameter (D), then the circumference (c) is (D) *pi. If you know the circumference (C), then the diameter (D) is (C)/pi. circumference is 2PiR
R is the radius.
so 2R is twice the radius (a.k.a. The Diameter)
That leaves you with
Circumference=Diameter*Pi
The circumference can be found by multiplying the diameter by pi, and the diameter can be found by dividing the circumference by pi.

What is the circumference of the circle in terms of pi?
pi = circumference/diameter circumference = pi*diameter or 2*pi*radius
What is the relationship between diamter and circumference?
circumference = pi*diameter or pi = circumference/diameter
What is the diameter of a circle if the circumference is about 46 units?
Circumference = (pi) x (diameter)Diameter = (circumference)/(pi) = (about 46)/(pi) = about 14.6423 (rounded)
What is the equation to get the diameter from the circumference?
Since the circumference is Pi times the diameter then divide the circumference by Pi (3.14159) to get the diameter
Find the diameter of a circle if the circumference is 24.5?
Circumference = diameter(pi) so divide the circumference by pi to get the diameter.
