A sphere in space with center (h, k, l) and radius r has equation

Four given points in space suffice to determine the values of h, k, l, and r. In Problems 21 and 22, find the center and radius of the sphere that passes through the four given points P, Q,R, and S.

P(11, 17, 17), Q(29, 1, 15), R(13, - 1, 33), S(-19, -13, 1)

(x-h)² + (y-k)² + (z − 1)² = r².
