Points A, B, C and D are placed in that order on a line so that AB = 2BC = CD. Express
BD as a fraction of AD.
If the radius of a circle is increased by two units, find the ratio of the new circumference to the new diameter.

However, they are "similar", so they also expand in width and depth as the height changes
such that they are magnified versions of each other.
The volumes are in the ratio
The capacities of the others can then be found.
