It is also a transcendental number, meaning that it is not the root of any non-zero polynomial that has rational coefficients. π is an irrational number meaning that it cannot be expressed exactly as a fraction (though it is often approximated as ) and its decimal representation never ends or has a permanent repeating pattern. The radius, diameter, and circumference of a circle are all related through the mathematical constant π, or pi, which is the ratio of a circle's circumference to its diameter. The figures below depict the various parts of a circle:
Diameter: the largest distance between any two points on a circle by this definition, the diameter of the circle will always pass through the center of the circle.It is equal to half the length of the diameter. Radius: the distance between any point on the circle and the center of the circle.
Center (or origin): the point within a circle that is equidistant from all other points on the circle.It can also be defined as a curve traced by a point where the distance from a given point remains constant as the point moves. More specifically, it is a set of all points in a plane that are equidistant from a given point, called the center. Radius (R)Ī circle, geometrically, is a simple closed shape.
