Question

Find an equation of the sphere with center (3, -1, -1) and radius 4

Answer 1

\[(x-h)^2+(y-k)^2+(z-l)^2=r^2\]

Answer 2

where the center is
\[(h,k,l)\]
and r is radius

Answer 3

just fill in the blanks:
\[(x-\_)^2+(y-\_)^2+(z-\_)^2=\_^2\]

Answer 4

(x-3)^2+(y+1)^2+(z+1)^2 =16

Answer 5

\[(x-3)^2+(y+1)^2+(z+1)^2=16\]
