A)   top part  = cone   =  pi * r^2 * h  / 3

       bottom part  = cylinder  =   pi * r^2 * h

 

B) top part volume  =  {  the radius  = diameter / 2}   =  3.1416 * (27/2)^2 * 9 / 3  ≈

 

1718 ft^3

 

C) bottom part volume  =  3.1416 * (27/2)^2 * 21 ≈ 12024  ft^3

 

Total volume  =   ( 1718 + 12024)  ft^3   =   13742 ft^3

That's disgraceful CPhill.

 

Why are you doing this persons homework for him/her ?

 

Help by all means, but you shouldn't be answering the whole of the question.
