Question

how do i solve this?

Answer 1

its a 3d sphere, with each value corresponding to an axies.

Answer 2

its similar to an equation of a circle.

The equation will equal the given radius.

Answer 3

the equation of a sphere is like the equation of a circle
If the sphere is centered at (a,b,c) and has radius r:

( x - a)^2 + (y - b)^2 + ( z - c)^2 = r^2

Answer 4

It is answer 1 because the three points are x,y,z
\[(x+1)^2+(y-5)^2+(z-8)^2=5 \]
It equals 5 because \[(\sqrt{5})^2 = 5\]
