wasn’t it 2 times that because the height of the shell was 2y? and hence 2(1-x)root(x)
fkkiwi:
I got 64pi/105 as well since 2 areas

I think it was an alright exam, up until Q16 - that's when it really hit hard :( don't think I got many marks there
APSODIFU:
What did everyone get for the one multiple choice about the graph and it asked about the concavity?
envisagator:
what was strange for me is that for the mathematical induction question 16.a, i couldnt prove the base case, even though it was simple cubic factorising, but still ended up proving it.
20 mins for the last question arhhhh
