The formula for working out the circumference of a circle is:
pi (3.14) x diameter
OR
pi (3.14) x 2 x radius
The diameter of a circle is the length of a line that goes right through the middle of the circle and touches on both sides.
The radius of a circle is half of the diameter.
Divide the circumference by 3.14159265 (3.14 for rough approximation) to find the diameter of a circle.
It is the ratio of the circumference (C) and the diameter (D) of a circle. Using pi and the diameter of a circle, you can work out the circumference.
The circumference of a circle with a known radius and can calculated using the following formula: C = 2Π(r)
The circumference of any circle divided by its diameter is always equal to pi. With this information we can work out various properties of the circle such as its circumference or its area.
16.55cm - If you want to work it out, you will need to divide the circumference by pi.
Circumference of a circle = diameter*pi Diameter of a circle = circumference/pi
The value of pi = circumference/diameter
The circumference of a circle is the perimeter of the circle for a given diamater.
c=2*pie*r c= circumference r= radius.
Work it out the circumfrance of a circle is pie x the diameter!
The perimeter of a circle is its circumference
The perimeter of a circle is its circumference
