1-Find the volume of the solid of revolution obtained rotating around  the y-axis the region determined by y=(x+4)^1/2, and the y-axis.
2-Find the volume of the solid of revolution obtained rotating around the x-axis a circunference with center on (5,0) and radio=2.
3- Find the volume of the solid of rotation obtained by spining the region determined in the first quadrant by y=(x^3/2)(e^ -x).

Answer
Hi, Graciela,

I am afraid that if you ask me to do all your homework there wouldn't be time to get it all back to you when you need it.

So, please pick ONE of these examples and send it.  I'll try to get it back to you quickly and you could then send another.  Perhaps, of course, the solution to the first one would give you the clue as to how to do them all.
