For the sphere with equation x - 1 2 + y + 2 2 + z + 4 2 = 36 , finda) the centerb) the length of the radius.

To determine

(a)

To find:

The centre for the sphere with equation x-12+y+22+z+42=36.

Explanation

The given sphere equation is x-12+y+22+z+42=36.

The equation of the sphere with centre h, k, l and radius length r is given by

x-h2+y-k2+z-l2=r2

Writing the given equation in the form of the general equation

To determine

(b)

To find:

The radius of the sphere with equation x-12+y+22+z+42=36
