Cover the Community needs
(explanation)

This exercise is a physical model of a particular task from the general mathematical problem of covering one geometrical shape with several other.

In this case the bigger circle has the diameter A, while the smaller circles have the diameter of approx 0.609A as shown on the far left. The basic diagram how to place all the five yellow circles so that they fully cover the red one is shown in the illustration.

This exercise shows that community needs can be covered only if various circles work collaboratively and in tandem.
