Have you drawn the graph? It's pretty straight forward, it's a basic disk method problem. Read this:
Pauls Online Notes : Calculus I - Volumes of Solids of Revolution / Method of Rings
Consider the region bounded by y = x2 + 7, x = 3, the x-axis and the y-axis.
Rotate the region about the y-axis and show how to find the volume of the resulting solid.
Any help? (If anyone could point me to a good tutorial, that would be cool too)
