The standard form of an equation of a circle is x - h 2 y - k 2 r 2. How to find the standard form and the general form of the equation of a circle with a given center and radius. This calculator can find the center and radius of a circle given its equation in standard or general form.
X 2 y 2 4.
The general equation of a circle is where A C and have the same sign. The teacher will present the equation of a circle with the center hk an radius r is given byx-h 2 y-k 2 r 2 ---- Standard Form where hk is the center of the circleThe teacher will discuss the formula x-h 2 y-k 2 r 2 with the given examplesThen to find the general form with Ax 2 By 2 Cx Dy c 0Example 1. So the required equations are x 2 y 2 - 10y 0 and x 2 y 2 10y 0. The center of a circle is located at 2 7.
