Challenge


Assume there is a wooden ball and you drill a cylindric hole through its center
so that the remaining spherical ring has a height of 4 units (cm/inch).
What is the volume of the remaining spherical ring?

For better understanding see and touch the following picture.

Hint: It's much easier to find the solution if you take it for granted there is really a solution, even with missing diameter of the ball or the cylindric hole.
