Answer 1

`\textit{equation of a circle}\\\\ (x- h)^2+(y- k)^2= r^2 \hspace{5em}\stackrel{center}{(\underset{h}{0}~~,~~\underset{k}{0})} \qquad \boxed{\stackrel{radius}{\underset{r}{8}}} \\\\[-0.35em] ~\dotfill\\\\( ~~ x - 0 ~~ )^2 ~~ + ~~ ( ~~ y-0 ~~ )^2~~ = ~~8^2\implies (x +0)^2 + (y +0)^2 = 64 \\\\\\ ~\hspace{23em} x^2+y^2=64`
