An arc
The fraction of the circumference of a circle can be expressed in relation to its diameter. The circumference (C) is calculated using the formula C = πd, where d is the diameter. Thus, the fraction of the circumference to its diameter is π:1, meaning that for every unit of diameter, the circumference is approximately 3.14 times that length. This ratio is a fundamental property of circles.
circumference = 2*pi*radius or pi*diameter
Circles do have a perimeter, which is known as the circumference. The circumference is worked out by multiplying:2, Pi, Radius (r)Pi, Diameter (d)Hope that's helpful for you!
It is part of a curve. If that curve happens to be a circle, then it is a fraction of a circumference but it need not be.
Then they are similar.

The circumference of a circle = pi*diametre = 2pi*radius
The equator.
That is called the perimeter; in the case of round shapes such as circles or ellipses, it is usually known as the circumference.
It is part of a curve. If that curve happens to be a circle, then it is a fraction of a circumference but it need not be.
Then they are similar.
Pi times the diameter of a circle gives its circumference.
The ratio of the circumference of a circle to its diameter is Pi. (3.14159)
