Hi, is it just me or does this question not make sense? Is anyone able to do this and show me how to do this? A friend of mine has been sent this question but they haven't even been shown how to do something like this and they can't work out how they're meant to convert cm cubed to cm squared. They were able to work out the area of the curved rectangle to make 1856.0226cm2 and they then multiplied this by 525 to get 974411.86 cm2 total area to be painted on the 525 vases, but where do they go from there? I said I'd help but it seems like there's an error in the question to me. Thanks.
A company makes 600 cylindrical vases. 12.5% of vases are discarded due to faults. The sides of the remaining vases will be painted either blue or white. They have
800 000cm³ of blue paint and will use all of this up before painting the rest of the vases with white paint. If each cylindrical vase is 32.3cm high and 18.3cm diameter, what is the probability that a vase picked at random will be blue? Give your answer as a decimal.
