    Well...

    Nah, I just haven't liked any uni I've seen or been to other than the Scottish ones. Just have the slight issue that I haven't been accepted to either of them I've applied to yet.

    Fair enough, good luck. Which Scottish unis are they then?

    Haha. Glad we got the same. Was afraid I'd made a silly sign error or something.

    Sorry to bother people again but can someone help me with this question? It's volumes of revolution (c4) again.

    I just don't really know how to approach this problem - I tried integrating m^2x^2 but that ended up in a bit of a mess...

    Thanks again!

    You're on the right track but you need to write m in terms of r and h and you would need to integrate between the limits of h and 0.

    Thank you! So something like this (I hope)? But how do you integrate when there are 3 different letters/variables??

    r and h aren't variables, they're just the coordinates so they are constants in this case. You only need to integrate with respect to x.
