That won't get you anywhere. You just have to make a start.

You managed to do part (i) yourself the other day and get the correct answer

Do you know the corresponding formula for rotation about the y-axis?

Have you attempted the integration?

Yeah I've attempted it several times but it doesn't give me an exact answer as required in the question

Post the attempt? You have to invert the function first, y = f(x) and then just proceed as normal but in terms of y rather than x.

Can you post your working?

Do you know what the answer should be?

I'm going out shortly so won't be able to look till later, but I'm sure someone else can check your working if you upload it
