Answer:

61.7% of container A is empty after the pumping is complete.

Step-by-step explanation:

The volume of a cylinder is calculated by the formula B×h, where B is the area of the base, or radius²×π.

The volume of cylinder A is 9²×π×10=810π.

The volume of cylinder B is 5²×π×20=500π.

The percent that will be used to fill container B is the complete volume of B out of A: [tex]\frac{500}{810}[/tex] ≈.61728395 which is 61.7% rounded to the nearest tenth.
