This lesson focuses on defining a circle, presenting its equation in two different forms (standard and general), and giving examples of how to...
The general equation of a circle is (x - a)2+ (y - b)2= r2, which represents a circle having the center (a, b) and the radius r. This equation of a circle is simplified to represent the equation of a unit circle. A unit circle is formed with its center at the point(0, 0)...
For two equations ax + by + c = 0 and px + qy + r = 0, it will have no solution when a/p = b/q ≠ c/r. What is the Equation of a Circle? The equation of a circle with radius r and center (x1, y1) is (x − x1)2 + (y − y1)2 = r2....
Radius –Radius is the distance from the centre of a circle to any point on the boundary of the circle. Diameter –Diameter is the line from one point on the boundary of the circle to another point and passing through the centre of the circle. It is twice the length of the radius. Ch...

The meaning of EQUATION OF THE CENTER is the difference between the place of a planet as supposed to move uniformly in a circle and its place as moving in an ellipse.
The equation of a circle is the algebraic equality that describes it given its radius and its center. In this lesson, we saw two forms of the equation: the standard form and the center-radius form. What is the center of the circle on a graph? The center of the circle on a graph ...
