b. A yoghurt pot can be approximated to a cylinder that is open at one end, with the following dimensions: height 78 mm, external diameter 90 mm and constant material thickness 0.3 mm. This is illustrated below. 0.3 mm scale) 90 mm 78 mm 0.3 mm Cylinder used to represent the yoghurt pot (not drawn to i. Given that the density of PP is 900 kg m-3, calculate the mass of one of the yoghurt pots in grams to 1 decimal place. ii. A different manufacturer makes yoghurt pots which weigh 9 grams each. Assuming each empty pot has a sale value of 3 pence, estimate the value added from the transformation of one tonne of PP granules into yoghurt pots. You can assume that a tonne of PP granules costs £1900 and there is no waste in the manufacturing process. Explain each step in your working. b.
