Answer: 3617.28 cubic millimeters.
Step-by-step explanation: I used the formula of a sphere since a gumball is a shape of a sphere and plugged the radius into the formula.
I got that the volume of a single gumball is 288π cubic millimeters.
Since there are 4 gumballs, i multiplied the volume by 4.
The total volume of the four gumballs add up to be 1152π .
Lastly, I multiplied 1152 by pi
and got the answer to be 3617.28 cubic millimeters
The answer is 21 because 189 divided by 9 is 21
