Find the equation of the circle circumscribing a square ABCD with side l and AB and AD as coordinate axes

Answer 1

centre ${}^{\prime }{o}^{\prime }=\left(\frac{1}{2},\frac{1}{2}\right)$

$AC:-\sqrt{2}$

$AO:-\frac{1}{\sqrt{2}}$

$e{q}^{n}ofcircle{\left(x-\frac{1}{2}\right)}^2+{\left(y-\frac{1}{2}\right)}^2={\left(\frac{1}{\sqrt{2}}\right)}^2$

${\left(x-\frac{1}{2}\right)}^2+{\left(y-\frac{1}{2}\right)}^2=\frac{1}{2}$ Answer.
