pls help me with my homework.

Find the volumes of the solids generated by revolving the regions bounded by the graphs of the eq’ns about the given lines:

1. y=sqrt3, y=0, y=3
a.) about the x-axis
b.) about the y-axis
c.) about the line x=3

2. y=x^2 , y=4x-x^2
a.) about the x-axis
b.) about the line y=6

3. Use the shell method to find the volume of the solid generated by revolving the plane about the y-axis:
y=4x-x^2 , x=0 , y=4

Uh, is eq#1 supposed to be $y = \sqrt{3x}$ perhaps?  It can't be $y = \sqrt{3}$ as that just gives us 3 parallel lines.
