ganeshie8 · Answer

compare it wid standard circle equation :

$(x-h)^2 + (y-k)^2 = \color{red}{r}^2$

ganeshie8 · Answer

$\color{red}{r}$ is the radius

anonymous · Answer

i dont get how i solve this.

ganeshie8 · Answer

given equation :-

$(x -5)^2 + (y + 2)^2 = 64 $

$(x -5)^2 + (y + 2)^2 = \color{red}{8}^2$

ganeshie8 · Answer

comparing wid the standard equation, r = 8, so radius = 8
