For the cone and cylinder I got 14/3 (silly me I actually put 4.6 recurring so will lose a mark) but you had to calculate the volume of the cone, the volume of the cone + cylinder filled in 4 hours, then divide that by 4 to work out the rate of volume filled / hour (I think it was 6 pi / hour if my memory serves me correctly), then times that by 7 to get the total volume of the cylinder, then see what would need to times by 9 (the radius of the cylinder's base) in order to get the total volume.
Then you have the height!
Long question, not necessarily hard, but I got the unit wrong... (facedesk)

What did other people get for harder questions? Like the graph transformation, on the last part of that question was it just translate (0/-4)?

i had a **** teacher who didnt teach us A questions properly. because it was i think a 4 mark question, would you get marks if you work out the volume of the cone?
