Find an equation of the sphere through the point (4,3,-1) and has center (3,8,1).

Step-by-step explanation:

The general equation of a sphere is as follows:

In which the center is , and r is the radius.

In this problem, we have that:

So

through the point (4,3,-1)

This leads us to find the radius.

So the equation of the sphere is:

2
