To get the diameter d is to divide the circumference C by pi. d = C / pi
If you know the circumference, the ration of the diameter to the circumference is π, so diameter = circumference/π If you have the radius, diameter = 2 x radius
You can either measure it, or calculate it if you know the diameter (radius = diameter / 2), or the circumference (radius = circumference / (2pi)).
The diameter of a circle can be found without the circumference using the formula d = 2r. This formula requires that you know the radius of the circle which is half of the diameter. To calculate the diameter you need to multiply the radius by 2. For example if the radius of the circle is 4 then the diameter would be 8 (4 x 2 = 8).You can also find the diameter of a circle if you know the circumference. To do this use the formula c = d. By rearranging the equation you can calculate the diameter as d = c/. For example if the circumference of the circle is 12.5 the diameter would be 4 (12.5/ = 4).
circumference of a circle = pi * diameter.
Diameter = circumference/pi
If you know the circumference, the ration of the diameter to the circumference is π, so diameter = circumference/π If you have the radius, diameter = 2 x radius
Multiply the diameter by Pi as the formula Pi x d = Circumference. Where d stands for diameter.
If by "it" you mean a circle, once you know the diameter, you can calculate its radius, its circumference, and its area.

Assuming you are talking about a circle:* If you know the radius of the circle, multiply that by 2. * If you know the circumference of the circle, divide that by pi. * If you know nothing, you need to measure either the radius, the diameter, or the circumference.
In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second circle the diameter is 14 when the circumference is 44?
Divide the known circumference by pi to find the diameter of the circle.
circumference of a circle = pi * diameter.
Divide the circumference by pi.
