Modeling) Volume of a Sphere The formula for the volume of a sphere is \(V ( r ) = \frac { 4 } { 3 } \pi r ^ { 3 }\) , where \(r\) represents the radius of the sphere. Construct a model function \(V\) representing the amount of volume gained when the radius \(r\) (in inches) of a sphere is increased by \(3\) in.

Answer

\(V ( r ) = \frac { 4 } { 3 } \pi ( r + 3 ) ^ { 3 } - \frac { 4 } { 3 } \pi r ^ { 3 }\)
