A homeware company has been approached to manufacture a cake tin in the shape
of a "ghost" from the Pac-Man video game to celebrate the 45th Anniversary of the
games launch. The base of the cake tin has a characteristic dimension / and is
illustrated in Figure 1 below, you should assume the top and bottom of the shape
can be represented by semi-circles. The vertical sides of the cake tin have a height of
h. As the company's resident mathematician, you need to find the values of r and h
that minimise the internal surface area of the cake tin given that the volume of the
tin is Vfixed-
2r
