Question

What is Equation of circle?

Answer

Equation of circle is a y is the radius and (h, k) is the center then the equation of such a circle is
${\left(x–h\right)}^2+{\left(y–k\right)}^2=y^2$
$\mathrm{or }{x}^2+y^2+\alpha x+\beta y+y=0$
$\mathrm{in\; which }\alpha =–2$
$\beta =–2k$
$\gamma \; =h^2+k^2–y^2$
