Of a circle: divide the length of the circumference by the value of Pi (about 3.14159). The answer is the diameter. Half of the diameter is the radius
Diameter of a circle = circumference/pi
If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).
If a circle has a diameter of 14, the circumference is: 43.98.
A circle with a circumference of 11.25 has a diameter of: 3.581
Circumference = diameter*pi
Because the ratio of the circumference to the diameter of every circle is pi. So circumference = pi*diameter.
pi*diameter = circumference Rearrange the formula so as the diameter is the subject of the formula: diameter = circumference/pi diameter = 7/pi = 2.228169203
A simple formula to calculate the circumference of a circle: so in this case:
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
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
Divide by 3.14
The circumference of EVERY circle is (pi) times (the diameter).Now you can calculate the circumference of not only that particular circle, butalso the circumference of any other circle that you'll ever meet in the future.
To calculate circumference you find a circle's radius or diameter. You do diameter times pi or radius times 2 times pi. Then you have circumference!Read more: How_do_you_calculate_circumference
Circumference of a circle = 2*pi*radius or pi*diameter
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
