Hello, I asked a question the other day and thank you for the responses

 

I have a new question which I think I am right on but the website says is incorrect,

 

Find the volume when the region between the y-axis and the curve y = x^2  on $x\in[0,2]$ is rotated about the y-axis.

 

I believe the answer is 64pi/5 and I did use the formula they gave us, but it still doesn't work. Am I missing something?

Are you missing something ? Obvously yes.

Correct answer is 8pi.
