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. pins program in dcWebThe equation of the circle with center (5, 2) and point (11,10) on the circle is {eq}(x-5)^2 + (y-2)^2 = 100 {/eq}.
