Yes, if you're calculating circumference from radius or diameter. Pi is the symbol used to represent the ratio of circumference to diameter of any circle: pi = c/d

This can also be written as c = pi*d. And has been noted, pi is approximately 3.14

What does pi have to do with circumference?

Pi has to do with circumference, because if you divide the circumference of a circle by its diameter, you always get pi (which is around 3.14).

Why the formula of circumference of circle always constant?

Because:- circumference/diameter = pi and when the formula is rearranged circumference = pi*diameter

What two measurements can you divide in a circle that will always give you an answer of pi?

They are: circumference/diameter = pi and circumference/2*radius = pi

What do we call the ratio of a circle's circumference to its diameter?

Pi is the ratio of circumference to diameter. C/d=pi always!!!

Is it possible to draw a circle whose ratio of circumference to diameter is not pi?

No, the circumference divided by the radius will always be pi for a circle.

The area of a circle is 16 pi?

What is the ratio of the circumference to the diameter for a circle is?

The circumference is always the diameter multiplied by the value of Pi.

How do you find the diameter of the circumference if a circle?

There is no such thing as "the diameter of the circumference" of a circle. A circle has a diameter, and a circle has a circumference. If you know one, you can always figure out the other one, because they're very tightly connected. Circumference = (diameter) times (pi) Diameter = (circumference) divided by (pi) "pi" = about 3.1415926536 (rounded). You can use 3.14 and your answers will be very close.

Why do people use Pi?

people use pi to find the circumference of a circle.

Is the radius one fourth of the circumference?

No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)

From what does pi derive from?

Pi is a number (which is 3.14....) which you will always get when you divide a circumference of circle by its diameter...

How do you use pi to determine circumference?

Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
