The circumference of a circle is calculated using the following formula:
c = 2 π r
where:
c is the circumference
r is the radius
π is the constant of pi (3.14159....)
Since the radius is equal to half of the diameter, this formula can also be written as:
c = π d
Or, alternatively:
d = c / π

What is the ratio of the circumference to the diameter for any circle?
The circumference of a circle is 3.14... times its diameter.circumference = diameter X pi
What is circumference in terms of pi?
As pi is the ratio of the ratio of the circumference (C) of any circle to its diameter (d), the circumference of a circle in terms of pi is: C = pi x d The circumference of a circle is pi times its diameter or 2 pi times its radius (since a diameter is 2 times the radius).
What does the ratio of the value of pi come from?
Any circle's circumference divided by its diameter has a value of pi
What is the diameter if the circumference is 84?
For any circle . . .Diameter = circumference/pi .
Why is pi always 3.14?
Because pi is a constant. It is the ratio between the circumference and diameter of any circle (assuming it is a perfect circle).
The ratio of the circumference and diameter any circle?
The ratio of the circumference of a circle to its diameter is Pi. (3.14159)
Ratio of the circumference and diameter of any circle?
The ratio of the circumference of a circle to its diameter is Pi. (3.14159)
The ratio of circumference and diameter of any circle?
The circumference of any circle is: diameter times pi The circumference of any circle divided by its diameter is the value of pi
Why is pi used in circle?
Because the ratio of the circumference of any circle to its diameter is pi.
What is the ratio to any circles circumference to the diameter?
The ratio of the circumference of a circle to its diameter is Pi. (3.14159)
What is the circumference of a circle with a 25ft diameter?
Pi is, by definition, the ratio of a circle's circumference to its diameter. It follows that the circumference of any circle is pi times its diameter.
What is the ratio of the circumference to the diameter for any circle?
The circumference of a circle is 3.14... times its diameter.circumference = diameter X pi
What is pi in a circumference?
Pi is the ratio of the circumference of a circle to the diameter. Thus for any circle, if you divide the circumference by the diameter, you get a value close to pi.
Find the ratio of the circumference to the diameter for each circle 3?
For any circle in a plane, the ratio of circumference to diameter is a number called pi, approximately 3.14.
What do diameter and circumfrance have to do with pi?
In any circle, the ratio of circumference to diameter is (pi).
What is calles the ratio of circumference to diameter of any circle?
pi
Explain Where the constant ratio of pi comes from?
If you have a circle ... any circle ... and you measure its circumference, measure its diameter, and divide the circumference by the diameter, the answer is always the same number, which people have decided to label with the name "pi". "Pi" is the ratio of a circle's circumference to its diameter, but "pi" is not a rational number, since it's not the ratio of any two integers.
