Back 4 more help. Volume of a Solid

I really need help with these volume problems.

1. y=e^x [1,2] rotated about y-axis

write integral for the volume of the solid formed
integrate algebraicallyand use sesults to find volume exactly (in terms of e, pi, etc)

2. y=3sinx [0,pi]

find volume of the solid formed by rotating R (area under the graph) about the y axis

find volume of the solid formed by rotating R abot the x axis.
