From Guy:
Le directeur d'un cirque a retenu cinq numéros pour composer son spectacle : les chiens savants, l'illusioniste, les clowns, les tapézistes et les acrobates.
- de combien de façons peut il composer son spectacles?
- En supposant qu'il y ait équiprobabilité dans le choix de la composition du programme, calculer la probabilité de chacun des événements suivants:
- les clowns terminent le spectacle
- les acrobates débutent ou terminent le spectacle
- les trapézites suivent immédiatement les clowns
- les clowns sont séparés des chiens savants par les trapézistes et seulement par eux.

The volume of water in a sphere shaped water tower |
2006-05-14 |
|
From Dan:
I work in the water industry, providing automatic controls for water systems. I was wondering if there was a formula for calculating the volume of water in a sphere shaped water tower? With the use of a pressure gauge we know the elevation of zero water {the bottom of sphere) and the overflow elev. (near the top of sphere) I would like to calculate how many gallons are at any elevation in between.
