What is the distance formula? |
When you take Point 2 values and subtract Point 2 values to find their vector. Then you take the magnitude of that vector. |

|
Show that x |
You assume a point of P = (x, y, z). The point is only on the sphere if if the magnitude of PC=radius. Squaring both sides you get Magnitude PC squared=radius squared. Or: (x-h) squared, + (y-k) squared,+(z-l) squared,=radius squared. |
