Best ResponseYou've already chosen the best response.0its fine. You could use the calculater to see where these functions intersect. Without one, just set the equations equal to eachother and solve (do this and tell me what you get)

Best ResponseYou've already chosen the best response.0that shows you what I set up for my integral. Its hard to explain via chat but try this: pi*(outter radius)^2  pi*(inner radius)^2

Best ResponseYou've already chosen the best response.0alright thanx but why did u square each equation? how did u know to do that?

anonymous

Best ResponseYou've already chosen the best response.0thats the volume formula

anonymous

Best ResponseYou've already chosen the best response.0because when you rotate the shape around the xaxis its 3dimensional. and you subtract the inner radius because thats the hole the shape makes when you rotate it. (so the shape looks like a doughnut)
