Diameter = circumference/pi
Circumference = pi*diameter or 2*pi*radius
Divide the circumference by pi, and that will give you the diameter.
Since circumference is found by multiplying pi by the diameter of the circle, the diameter can by found using the inverse operation. diameter = circumference/pi
circumference = π x diameter π = 3.14159...
It is the ratio of the circumference (C) and the diameter (D) of a circle. Using pi and the diameter of a circle, you can work out the circumference.
Diameter = circumference/pi
Circumference = pi*diameter or 2*pi*radius
Divide the circumference by pi, and that will give you the diameter.
If: circumference = pi*diameter Then: pi = circumference/diameter
Since circumference is found by multiplying pi by the diameter of the circle, the diameter can by found using the inverse operation. diameter = circumference/pi
using the formula circumference=diameter X pi: circumference=diameter X pi circumference/pi=diamter X pi/pi circumference/pi=diameter therefore, diameter=circumference/pi diameter=12mm/3.14 diameter=3.821mm
circumference = π x diameter π = 3.14159...
Diameter = Circumference/pi
Because the ratio of the circumference to the diameter of every circle is pi. So circumference = pi*diameter.
Multiply the diameter by pi, and the answer will be the circumference.
Circumference is found by multiplying the diameter by pi (approx. 3.14). Using this formula, A circle with a diameter of 60 inches has a circumference of approximately 188.4 inches.
