For a class project, I have been asked to find the volume of the area bounded by two functions, with cross sections of equilateral triangles.
The two functions in question are
y = xsinx
y = xsinx ,
And I need to find the volume that would result if the cross sections were equilateral triangles.
The interval upon which I have to do this is [2π, 2π].I am aware that I have to integrate an area function in order to obtain the volume, but I am confused about how to get an area function for this.
Can anyone help? Thanks!

I don't know what you mean by the volume of an area, or the cross section of an area.

I;m sorry, I did not state that very well. I'm still new to calculus.
I think I have figured it out. Thank you for responding anyway.
