Calculus III:
Find an equation of the largest sphere with center (7, 6, 9) that is contained in the first octant.
I assumed the radius would be 6 since it was the smallest of the three, and that the problem would be
(x7)^2 + (x6)^2 + (x9)^2 = 36, but that turned out to be wrong.
Where is the "first octant"?
Would that be the XYplane?

Best ResponseYou've already chosen the best response.0youre right in saying that the 6 is the limiting factor here. I think you have the right idea, just try tweaking your equation slightly like this: \[\left( x7 \right)^2+\left( y6 \right)^2+\left( z9 \right)^236=0\]
