Answer:
Part 1) The new distance from the water to the top of the tank is 
Part 2) The maximum number of balls that can be put into the tank with the tank not overflowing is 95
Step-by-step explanation:
step 1
Find the total volume of the tank

step 2
Find the volume of the tank if the water level is two inches below the top of the tank

step 3
Find the volume of the glass sphere
The volume of the glass sphere is equal to

we have

assume

substitute


step 4
What is the new distance from the water to the top of the tank?
we know that

so
using proportion
Find how many inches correspond a volume of 

The new distance from the water to the top of the tank is

step 5
Find how many of these balls can be put into the tank with the tank not overflowing
we know that
The volume of one ball is equal to 
using proportion

therefore
The maximum number of balls that can be put into the tank with the tank not overflowing is 95
Experimental probability is the outcome during a certain experiment. add up the total number of times it was spinned. You should get 40. To find the experimental probability of each section, simply divide the number by 40. This will give you the percentage for each one. For example, spinner A. 14/40=.35 Multiply this by one hundred to find the percentage (35%). Do this for all and let me know if you need help converting them to fractions. :)
