Answer to Problem 22RE
The center is
Explanation of Solution
Given:
The equation of the sphere
Consider the equation of the sphere
The center and radius can be obtained by completing the square in the equation of sphere.
The standards form of the equation of the sphere whose center
Consider the equation of the sphere
To obtain the standard equation of the sphere, complete the square as follows:
By comparing the above equation by the general equation of sphere that is
Hence, the center is
