The circumference is the perimeter of a circle, total outer length of a circle.
Use 2 x (pi) x r to calculate the circumference, where (pi)= 3.142, r= radius of circle. :)

What formula is used to find the diameter when you know the circumference?
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
If you know the circumference what is the radius?
Circumference is calculated by 2pr So if you know the circumference, divide by 2, and then divide by p That answer will be the radius
When you know the circumference of a circle how do you find the diameter?
If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
How can i find circumference if you know diameter?
Circumference = Pi * diameter
If you know the circumference of a circle how do you get the diameter?
Divide the circumference by pi.
What is circumference if you know diameter?
The circumference is the diameter x 2.
How do you get the diameter if you only know the circumference?
Circumference is pi * d. Solve for d. d = Circumference / pi
How do you find the diameter of a circle when you know the circumference?
circumference/pi = diameter
How do you find circumference if you know diameter?
If you know the diameter and need the circumference you times the diameter of the circle by 3.14 also known as pie. That is how you get the circumference by only knowing the diameter. :)
How do know how to make out circumference and diameter if you only know the radius?
If you know the radius, then Diameter = 2 x (radius) Circumference = (pi) x (diameter) or Circumference = 2 x (pi) x (radius)
How do you find the raduis if you know the circumference?
Radius (not raduis) =circumference/(2*pi)
How do you fund the circumference of circle when you know the area?
You dived the area by the circumference of the circle.
