You can check you've got Q11 right by looking at the area of the circle at height 125cm which is 17671cm^2 and 10000 / 17671 gives you 0.57 as well so at least that's consistent (the height of the cylinder at that point would be 0.57cm)
How many marks would you lose if you forgot to convert litres to cm3 but did everything else
Probably 1 but they would follow it on! I did the same mistake
