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.
pi = circumference/diameter circumference = pi*diameter or 2*pi*radius
circumference = pi*diameter or pi = circumference/diameter
Circumference = (pi) x (diameter)Diameter = (circumference)/(pi) = (about 46)/(pi) = about 14.6423 (rounded)
Since the circumference is Pi times the diameter then divide the circumference by Pi (3.14159) to get the diameter
Circumference = diameter(pi) so divide the circumference by pi to get the diameter.
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
0.7161972439135291... Circumference = pi*diameter which yields circumference/pi = diameter 2.25/pi = diameter 2.25/pi = 0.7161972439135291...
Circumference = Pi x Diameter (Pi equals 3.14)
Circumference is Pi x Diameter so do Circumference divided by Pi to get the diameter :)
pi = 21.99/7 pi = circumference/diameter Just multiply your diameter by pi to get a circumference.
Circumference = Diameter*pi So diameter = Circumference/pi = 32*pi/31 = 32
the diameter mutliplied by pi is the circumference. From a different view the circumference divided by diameter is pi.
pi = circumference/diameter circumference = pi*diameter or 2*pi*radius
circumference = pi*diameter or pi = circumference/diameter
Diameter = circumference/pi = 17/pi
Diameter = circumference/pi = 17/pi
pi = circumference / diameter
