In order to calculate this you need the correct formula. The formula for the circumference of a circle is classified as pi x Diameter. It can also be written as pi.d.
Circumference is in essence the distance or length around a circle. _, correctly pronounced like pie, is an irrational number, which means that it cannot be written as a fraction. So to be sure, a good approximation of π is 3.14 when used in particular formulas.
Pie, or pi, is essential in calculating the circumference. Make sure you know where the centre of the circle is first. You will need to find the diameter, which is a line that touches two ends of circle and the centre.
You can then use this line accordingly, or the radius, alongside with π in order to calculate the circumference. All you need to do is multiply the radius by 2 to obtain the diameter.
Other things to note in a circle include the radius, which is a line that touches an outer part of the circle and the centre. It does not make contact with more than one part of the outside. You will be able to replace diameter with this for an alternative formula. To obtain a radius you need to divide the diameter by 2 to get the radius.
There are two formulas and, bearing in mind if you take into consideration that you already know the diameter then it will be a lot simpler to do the circumference. In mathematical terms the circumference of a circle in algebra is described as:
C = π x Diameter
or
C = π x(2 x Radius)
