The ratio is "pi" which is approximately 3.1416 or 22/7.
Pi is a transcendental, continuous decimal that can be calculated to large numbers of significant digits.

How do you represent the circumference of a circle as a function of its diameter?
Circumference = pi*diameter.
What does pi actually represent?
Generally, Pi is used to represent the rate of change of the circumference of a circle as it's diameter increases. This can be shown using the equation [circumference = Pi * diameter], that is the circumference of a circle is always Pi times larger than it's diameter.
How is the diameter and circumference on a circle approximate to pi?
the diameter mutliplied by pi is the circumference. From a different view the circumference divided by diameter is pi.
Who started using the symbol pi to represent the ratio of circumference to diameter?
Archimedes
How can you find the circumference of each circle and round to the nearest unit?
You take the radius (or diameter). If radius you times it by two (since it is half of the Diameter) then times the answer by 3.14. If diameter, times the diameter by 3.14. then round the decimals.
How do you get diameter from circumference?
Circumference is Pi x Diameter so do Circumference divided by Pi to get the diameter :)
How do you figure out diameter and circumference?
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
How do you find the diameter from the circumference?
Diameter = Circumference/pi
If you have your circumference how do you find the diameter?
diameter = circumference/pi
What is the diameter of a 12cm circle?
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
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
What is the circumference of A 13.5 Diameter circle?
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
