27. The Risk of Insurance: An investigation into asymmetric information and how being unsure about the future state of the world may lead us to be risk-averse.

28. Gabriel’s Horn: This figure has an infinite surface area but a finite volume, can you prove this?

29. Modelling the Shape of an Egg: Although it may sound easy, finding the surface area or volume of this common shape requires some in-depth mathematical investigation.

30. Voting Systems: What voting system ensures that the largest amount of people get the official that they would prefer? With 2 candidates this is logical, but what if they have more than 2?
