ANSWER
The length of the diagonal is 5 ft
EXPLANATION
The diagram of the rug with the diagonal is:
The diagonal and the sides form a right triangle, so we can use the Pythagorean theorem to find x, the length of the diagonal:
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
