WebThis equation is the same as the general equation of a circle, it's just written in a different form. Example Find the equation of the circle with centre \((2, - 3)\) and radius \(\sqrt 7\) . WebWe 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. So add 21 to both sides to get the constant term to the righthand side of the equation. x^2 + y^2 -4y = 21. Then complete the square for the y terms. x^2 + y^2 - 4y + 4 = 21 + 4.
