First you need to find the volume of each. Given a cylinder with radius 3cm and height 5 cm we can find the volume (π3^2*5) to be 45π. If we multiply this by the density (45π*19.3) we get the weight to be 2727.09 grams. I'll leave you to find the weight of the platinum given the volume of a cone is 1/3 BH.
