????@agentx5 do you think that you can help me with it?

anonymous · Answer

$$radius=\pm \sqrt{\frac{Area}{4\pi}}$$

I'm not sure what "S = 64" means

and then from the other question you closed already, the formula for a circle is
$$(x - h)^2 + (y - j)^2 + (z - k)^2 = r^2$$

center (h,j,k) and radius r ; you only need to adjust the center if it's offset from the origin.
