Solve the problem.
-A farmer's silo is the shape of a cylinder with a hemisphere as the roof. If the height of the silo is 118 feet and the radius of the hemisphere is r feet, express the volume of the silo as a function of r.
A) $V ( r ) = \pi ( 118 - r ) + \frac { 4 } { 3 } \pi r ^ { 2 }$
B) $V ( r ) = 118 \pi r ^ { 2 } + \frac { 8 } { 3 } \pi r ^ { 3 }$
C) $V ( r ) = \pi ( 118 - r ) r ^ { 3 } + \frac { 4 } { 3 } \pi r ^ { 2 }$
D) $V ( r ) = \pi ( 118 - r ) r ^ { 2 } + \frac { 2 } { 3 } \pi r ^ { 3 }$

The Answer of Solve the problem.
-A farmer's silo is the shape of a cylinder with a hemisphere as the roof. If the height of the silo is 118 feet and the radius of the hemisphere is r feet, express the volume of the silo as a function of r. 
A) $V ( r ) = \pi ( 118 - r ) + \frac { 4 } { 3 } \pi r ^ { 2 }$
B) $V ( r ) = 118 \pi r ^ { 2 } + \frac { 8 } { 3 } \pi r ^ { 3 }$
C) $V ( r ) = \pi ( 118 - r ) r ^ { 3 } + \frac { 4 } { 3 } \pi r ^ { 2 }$
D) $V ( r ) = \pi ( 118 - r ) r ^ { 2 } + \frac { 2 } { 3 } \pi r ^ { 3 }$

Solve the Problem V(r)=π(118−r)+43πr2V ( r ) = \pi ( 118 - r ) + \frac { 4 } { 3 } \pi r ^ { 2 }V(r)=π(118−r)+34​πr2

Solve the Problem $V ( r ) = \pi ( 118 - r ) + \frac { 4 } { 3 } \pi r ^ { 2 }$
