Multiplying the diameter by pi (approx 3.1416) will give you the circumference of the circle.
circumference of a circle = pi * diameter.
Circumference of a circle = pi*diameter or 2*pi*radius
circumference of a circle = diameter*pi or 2*pi*radius
the circumference of the circle divided by pi (button or 3.14) - Maths
pi is the ratio of a circle's diameter (the distance across it) to its circumference (the distance around it).
circumference of a circle = pi * diameter.
Circumference of a circle = pi*diameter or 2*pi*radius
The circumference of every circle is its diameter multiplied by (pi). For (pi), use 3.142 or 22/7 .
circumference of a circle = diameter*pi or 2*pi*radius
Circumference of a circle = 2*pi*radius or pi*diameter
The circumference of a circle is the distance around the outside of the circle. It could be called the perimeter of the circle. The circumference of a circle can be found by multiplying pi ( n = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If You know the radius, the diameter is twice as large.
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.
In order to find the diameter of a circle, you have to take the circumference of the circle and divide by Pi for which you can use the approximation: 3.14. So if the circumference of the circle is 60 inches, you divide that by Pi (3.14) and get a diameter of 19.0985 inches.
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi

A good strategy is to use whatever you do know about the circle, along with anyformula that relates the information you do have to the circumference of a circle.
pi is the ratio of a circle's diameter (the distance across it) to its circumference (the distance around it).
