Question: Cylindrical objects

Hi Everyone,

I want to draw a 3D cylindrical object with follwoing constraint:

(1) For z=0 to 5, it should be a cylinder with radius 2 units

(2) For z = 10 to 20, it should be a cylinder with radius 8 units

(3) Connecting piece between z=5 to 10 is a type of cylinder such that its radius increses from 2 to 8 as z moves from 5 to 10.

 

I know how to draw (1) and (2) individually, but can't make a connecting object.

Can anyone help me drawing that object?

Thanks in advance.
