Solids revolution
The graph is what I got for (g), is that right? And in order to get the volume I just need to use pi(r)^2h????

Re: Solids revolution
Your first question, I can't answer because it is not clear which part of the graph you intend as your answer. I see a cylinder and a cone inside the cylinder. What do you intend as representing the region described?

The formula $\pi r^2h$ gives the volume of the cylinder. Is that what you intended?

It just says to calculate the volume of the solid formed.... I'll just ask my teacher I guess.. Thanks though
