Answer: 
Explanation:
We need to know the volume of the cone that can be filled with bubble gum ball, but firstly we need to calculate the volume of the cone 
and the volume of the buble gum ball (a sphere) 
:
<u>Volume of the cone:</u>
(1)
Where:
is the radius of the cone
is the height of the cone
(2)
(3) This is the volume of the cone
<u>Volume of the gum ball:</u>
(4)
Where:
is the radius of the sphere (half the diameter)
(5)
(6) This is the volume of the gum ball
Know we are able to find the closest approximation of the volume of the cone that can be filled with bubble gum ball, by calculating the difference or substracting (6) from (3):
(7)
Finally:
(8)
