Equation of a circle how to#

Any point on the perimeter of the circle may suffice.įrom the above points, we now have basic information about the requirements for the equation of the circle. The next parameter we need to complete the equation of any circle is the point from which the circle passes. The equation will be formed around the radius of the circle. Since we know that a circle is the set of different data points equidistant from a given point (the center of the circle), the equation of the circle will be around this point. We require two things if we want to graph a circle on the cartesian plane. Thus we can say that a circle is a uniform figure. The distance from the center of the circle to any point on the circumference is always equal. The radius of a circle is the most essential for plotting it. When we plot any circle in a graph, we require two to four parameters. The entire circle is drawn around the radius. The parameters inside a circle are radius, chords, perimeter, and area. First, let us understand the concepts of circles.Ī circle is a closed figure which has no sides.

In this article, we shall learn how to graph a circle, the equations, and the concepts needed.īefore understanding the concept of the equation and graph of the circle, let us learn some important terms required to understand this article’s topics. The equation of the circle is required to draw it on the graph. Many concepts were discovered when the circles were drawn on a graph. This makes them unique and a good topic of discussion. Equation and graph of a circle are the only shape that has no edges.
