Divide the circumference by the value of Pi - that will give you the diameter.
Divide the circumference by 3.14159265 (3.14 for rough approximation) to find the diameter of a circle.
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.
The equation for finding the circumference of a circle is diameter times pi so reverse it to circumference divided by pi which leaves the diameter. The diameter is twice as big as the radius so divide the diameter by 2 and you will find the radius.
diameter*pi = circumference
Divide the circumference by the value of Pi - that will give you the diameter.
Divide the circumference by 3.14159265 (3.14 for rough approximation) to find the diameter of a circle.
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. :)
to find the diameter of a circle when you only have the circomference you: divide the circomference by pi (approx. 3.14)
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
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.
The equation for finding the circumference of a circle is diameter times pi so reverse it to circumference divided by pi which leaves the diameter. The diameter is twice as big as the radius so divide the diameter by 2 and you will find the radius.
Diameter of a circle = circumference/pi
Divide the known circumference by pi to find the diameter of the circle.
circumference/pi = diameter
diameter*pi = circumference
Diameter = circumference/pi
