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

The area of a square is
(length of a side) times (length of a side) .
So if you want to know the length of the side,
you have to find a number that gives you 81
when you multiply the number by itself.
That's called the "square root" of 81 .
Each side of your square is 9 units long.
Answer:
121
Step-by-step explanation:
so she saved $20 and that was 40% of the regular price, let's say the regular price is "x".
if 20 is 40%, what is "x" or namely the 100%?
Answer:
4.41
Step-by-step explanation:
you multiply 2.1 times 2.1
