How did you guys find it?

It went reasonably well for me I think - some of the later ones were tricky as always, but not anything too difficult imo. How did you find it?

It was sooooo good
it was great, did you get 330 for the surface area of the hemisphere question
i thonk i got it wrong

i loveddddddddd it tbh. I don't think i did amazingly but I thought the questions were really nice. except q8 (pressure of cylinder) bc that confused me since it was only 3 marks but we had to work out area and everything. i also didn't like q24 but whatever

yeah it wasn't 330 but i can't remember exactly what it was

it was fine tbh, although i didn't realise there was a question at the back, anyone not see it?

i think it was 320

it was 1099

X = 5.9 roughl, so you plugged it into formula ( 3 X pi X (2x)^2)

I managed to see it bc I knew that the exam board does that to take the mick sometimes, and the best thing was it was acc quite a nice question a cheeky little complete teh square

I basically made that 12x^2 pi, is that mathematically correct?
because (2x)^2= 4x^2
(4x^2)*3=12x^2
then times pi

what did you get for the hemisphere question ?

what did you get for the hemisphere question ?
If x was 5.9 roughly then wouldn't you multpily that by 2 to get r and then sub that into (pi r^2)+ (2 pi r^2)

or maybe it was 3 multiplied by x not 2, i can't remember tbh

can't remember tbh but i think i might have got it right judging by the chat on here bc i just did 12x^2pi and thats the answer, i initially misread it and i put the total surface area of the cone which took me ages and i felt like such a moron when i reread the Q and I had to do abt half the working but it wasn't too bad
