Could someone please help me with the following area and volume problems?

-Find the volume of the solid formed when the region bounded by the curves y=x^3 +1, x=1, and y=0 is rotated about the x-axis. How do I do something like this for a volume of the solid problem with three curves???

-Find the area bounded by the curves f(x)=x^3 +x^2 and g(x)=2x^2 +2x.
