Task of the Week: Nine Figures

Today’s best practice example in the Task of the Week focuses on composite geometric bodies with truncated cones and a sphere.

Task: Nine figures (Task number: 3780)

Determine the volume of one of those figures. Give the result in liters.

As mentioned, the figure can be divided into a large, a small truncated cone and a sphere. This step is an important step by ignoring smaller derivations and through the mental disassembly of the figure. Afterwards, a clever and accurate way to determine the respecitve heights and/or radii must be chosen. By adding the volumes, the total volume results. By specifiying four possible solutions via multiple choice, it is possible to determine the result by approaching and estimating.
