Question 912139: What is the furthest away that two points in space can be, if the first is on the surface of the sphere with center (1,-4,9) and radius 15 and the other is on the surface of the sphere with center (-3,10,-6) and radius sq root of 17?
Answer by Edwin McCravy(20054)   (Show Source): You can put this solution on YOUR website!
The distance between two points in 3D space is given by the
formula:



We use that to find the distance between the centers (1,-4,9) and (-3,10,-6).











To that we must add the radius of each sphere, since that's how much further
apart the two points which are furthest apart are than the centers are apart.
