The approximate difference in their volumes is 17.2 cubic inches
<h3>How to determine the difference in the volume?</h3>
The given parameters are:
Diameter, d = 2.8
Diameter, D = 3.8
The radii are the half of the diameter.
So, we have:
r = 1.4
R = 1.9
The volume of the balls is then calculated using:

The difference is then represented as:

Substitute known values

Evaluate
D = 17.2
Hence, the approximate difference in their volumes is 17.2 cubic inches

Answer:
The value of
is
.
Step-by-step explanation:
We need to simplify the numeric expression using property. The expression is as follows :

The property to be used is : 
This property is valid if the base is same. Here, base is x.
In this given problem, x = 4, a = 1/3 and b = 1/5
So,

So, the value of
is
.
