Thread: 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????

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 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
