Multiple Choice

Write an equation for the sphere with the given point as its center and the given number as its radius.
- $( 4,7,4 ) , \sqrt { \mathrm { r } }$

A) $( x + 4 ) ^ { 2 } + ( y + 7 ) ^ { 2 } + ( z + 4 ) ^ { 2 } = r ^ { 2 }$
B) $( x - 4 ) ^ { 2 } + ( y - 7 ) ^ { 2 } + ( z - 4 ) ^ { 2 } = r$
C) $( x - 4 ) ^ { 2 } + ( y - 7 ) ^ { 2 } + ( z - 4 ) ^ { 2 } = \sqrt { r }$
D) $( x + 4 ) ^ { 2 } + ( y + 7 ) ^ { 2 } + ( z + 4 ) ^ { 2 } = 2 r$
