dC/dr and just substitute r into it
should have found r = 2.92 (3 s.f.)

integrate both sections using the curve, should either did 192+34 or 162+64

I did the same method but took 1/8 separate. Took me ages that question because I spent so long trying to complete the square before I gave up and used the formula
15. I literally have no idea how anyone can get 100% UMS on edexcel maths papers, is it just pure luck? I mean, it's not particularly difficult to get an A but I don't think 90 minutes is long enough when some of the questions seem deliberately worded to catch you out.
16. It made my want to fight someone

hmmm you'll probably get half of the marks! it's okay
18. (Original post by PeachPlum)
i did that too. hopefully max 2 marks?.. what was it out of?
Looking at past mark schemes it'll cost us 2 marks.

20. Guys do you know how many marks does the second last question worth? I did square root of 25 instead cubic root.....but all the methods should be correct.
