- $( 4,7,4 ) , \sqrt { \mathrm { r } }$

• 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) \(( x + 4 ) ^ { 2 } + ( y + 7 ) ^ { 2 } + ( z + 4 ) ^ { 2 } = 2 r\)
