If you know the radius, double that to get diameter. If you have neither radius or diameter, then measure around the outside.

How do you calculate the radius of a turn based on a path or curve without knowing the circumference or diameter?

You cannot.


How do you find the circumference of a circle without knowing the area?

To find the circumference of a circle, you need only know the radius or diameter of the circle. The circumference of a circle is calculated as 2 x Pi x radius OR Pi x diameter. Pi is approximately 3.1415926.


Have multiplied the diameter by pi to find the circumference of a circle but still getting wrong answer?

You are correct that the circumference of a circle = pi * diameter. One possibility is that pi need to have a certain precision to have an answer to match your known solution. Without knowing more about your problem and the supposed answer, I cannot help you further. P.S. pi = 3.1415926535897932384626433832795... =======================


How many linear feet are in 157 diameter?

To find the linear feet in a given diameter, you need to know the circumference (or perimeter) of the object. The formula to calculate the circumference is circumference = π × diameter. Without the circumference, it is not possible to determine the linear feet.


How do you find the diameter without the circumference?

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).
