-A farmer's silo is the shape of a cylinder with a hemisphere as the roof. If the height of the silo is 66 feet and the radius of the hemisphere is $r$ feet, express the volume of the silo as a function of $r$ .

• A) \(V ( r ) = \pi ( 66 - r ) r ^ { 2 } + \frac { 2 } { 3 } \pi r ^ { 3 }\)
• B) \(V ( r ) = \pi ( 66 - r ) + \frac { 4 } { 3 } \pi r ^ { 2 }\)
• C) \(V ( r ) = \pi ( 66 - r ) r ^ { 3 } + \frac { 4 } { 3 } \pi r ^ { 2 }\)
• D) \(V ( r ) = 66 \pi r ^ { 2 } + \frac { 8 } { 3 } \pi r ^ { 3 }\)
