Ah, the infamous "bonus hole" cylinder, a perplexing concept indeed. You see, when it comes to calculating the volume of a cylinder, you typically consider the entire shape. However, in some twisted scenario involving a "bonus hole," one might be inclined to calculate only half of said hole for unknown reasons. Perhaps it's an attempt to conserve mathematical energy or just pure madness! Regardless, my advice would be to embrace the absurdity and leave no bonus holes uncalculated!
