Here is the problem: Find the volume of the solid formed by rotating the region enclosed by y=e^(3x)+1,y=0,x=0,x=0.7 about the y-axis. What I know is that I am supposed to solve for x since it rotates on the y axis. So I have y=e^(3x)+1 y-1=e^(3x) ln(y-1)=3x ln(y-1)/3=x Now what? I am not sure how I am supposed to solve this or what I do now. I am starting Calc II so this is new to me and i've never used logs before for this. What do I do, and how does it work for me to solve this?
