the 320 comes from r (radius of 8cm) squared (64cm squared) times the height (5cm) = 320cm cubed

Therefore 5 pi r squared = pi320 cm cubed

Thanks everyone! Very Happy

I asked my tutor as well last night and she said that it was 320pi centimetres cubed, but that because I'd put the symbol for pi and put centimetres cubed I would still get 2 marks out of the 4. Hoorah! Very Happy

Thank you all for your thoughts about the pesky question. Very Happy
