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
Um sounds nice i guess its kind of funny simplify hairy fractions
