What is the relationship between the diameter of a circle and its circumference called?
pi
How do you work out edge of a circle from diameter?
diameter X pi = circumference What you call edge is usually called circumference. pi = 3.1416
What is the ratio of the circummference of a circle to its diameter called?
pi = circumference of a circle divided by its diameter
Why is the number pi called pi?
The symbol pi (π) for the value was introduced by the English mathematician William Jones (1746-1794). Long before then, the numerical relationship between the diameter and circumference of a circle was known and used.
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 is the relationship between the diameter of a circle and its circumference called?
pi
What is the relationship called when a diameter and a circumference equal 3.14?
An impossibility because if the diameter is 3.14 then the circumference must be 3.14*pi
What is the relationship between diameter and circumference?
The distance across a circle through the center is called the diameter. The distance around a circle is called the circumference. Pi is the ratio of the circumference of a circle to the diameter. So,2 radius x Pi = circumferencePi is approximately 3.14159265358979323846...
What is 3.1425?
That is called pi, the ratio between the diameter and the circumference of a circle. Of course, 3.14159265 is more accurate.
Why 3 is a good representation for a relationship between the diameter and the circumference?
The ratio of circumference to diameter is a number called pi, equal to about 3.14159265. If you round this to 3, you are about 4.5% off. This is good enough for mental estimates; for calculations on paper and pencil, or calculator, I would at least use two digits after the decimal point, i.e., 3.14.
How do you find the diameter of a circle with the perimeter?
The equivalent of a "perimeter" in a circle is actually called its circumference. To get the diameter, just divide the circumference by pi.
How do you work out edge of a circle from diameter?
diameter X pi = circumference What you call edge is usually called circumference. pi = 3.1416
What is the formula for the circumfriss of a circle?
It is called circumference. This is usually calculated from the diameter (circumference = pi x diameter), or from the radius (circumference = 2 x pi x radius).
If a circle has a circumference of 100 feet what is the width?
With "width", I assume you mean what is commonly called the diameter - the distance through the center. The circumference is diamter x pi, therefore, the diameter is the circumference divided by pi. In other words, just divide the circumference by 3.14, approximately.With "width", I assume you mean what is commonly called the diameter - the distance through the center.

Circumference of a circle?
Boundry of circle is called circumference.
