If the equation of a circle is given in general form x2+y2+cx+dy+e=0, group the terms with the same variables, and complete the square for both groupings. This will result in standard form, from which we can read the circle's center and radius.
X2 + y2 = r2 , and this is the equation of a circle of radius r whose centre is the origin O(0, 0). The equation of a circle of radius r and centre the origin is x2 + y2 = r2 .
The general form of the equation of circle is: x2 + y2 + 2gx + 2fy + c = 0. This general form is used to find the coordinates of the center of the circle and the radius of the circle. Here, c is a constant term, and the equation having c value represents a circle that is not passing through the origin.
And then in general form. You've got the ax squared plus B Y squared. Plus CX plus dy plus C equalsMoreAnd then in general form. You've got the ax squared plus B Y squared. Plus CX plus dy plus C equals 0. So let's check out our first. Example.

The two most prevalent equation forms of a circle are: Standard Form: x-h2+y-k2= r2. General Form: x2 + y2+ 2gx + 2fy + C = 0.
Equation of a Circle: The standard form of the equation of a circle is ( x − h ) 2 + ( y − k ) 2 = r 2 where is the center of the circle and is the radius. Radius: The radius is the distance from the center of a circle to any point on the edge.

And then y2 and y1. We can continue to evaluate. Here negative five minus one equals negative six.MoreAnd then y2 and y1. We can continue to evaluate. Here negative five minus one equals negative six. And over on the right side in parentheses. Negative one minus seven equals negative eight.
A standard form equation looks like this: Ax + By = C where A, B, and C represent numbers. For example, a standard equation with numbers looks like this: 5x - 3y = 8 (A = 5, B = -3, and C = 8). If you are asked to solve for either the slope or y-intercept, you will need some formulas.
