We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius.
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.
The standard form of a circle's equation is (x-h)² + (y-k)² = r² where (h,k) is the center and r is the radius. To convert an equation to standard form, you can always complete the square separately in x and y.
General form of Equation of a Circle The general equation of any type of circle is represented by: x2 + y2 + 2gx + 2fy + c = 0, for all values of g, f and c.
If you are asked to write the equation in standard form, then you need to get rid of the fractions. Standard form is: Ax + By = C where A, B and C are integers (so no fractions).
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.
