6. Mateo and Teresa will soon celebrate their son's birthday, the details that they are going to give to their guests are conical, they have not yet been decided by size, but they want them to have the largest possible capacity. The saleswoman in the store assures them that to obtain the highest volume, the radius and the height must be the same measurement; Teresa suggests that to obtain a greater volume, the height of the cone should be double the radius, while Mateo considers that to have a greater volume they should double the radius and reduce the height by half. According to the previous approaches, it can be considered that:

a

The cones raised by Mateo and Teresa will have the same volume, since the relationship between radius and height is maintained.

b

The cone with more volume is the one that Mateo considers as it is wider.

c

The volume of the cone with the measurements that the seller assures is double the volume of the cone that Teresa lifts.

d

The cone with the largest volume is the one lifted by the seller, since it has the same height and radius.
