When we perform a study, we test a specific hypothesis to see whether our hypothesis is supported by the data or not. If our hypothesis is not supported by the data, then we can argue that a specific argument (that would be important for this hypothesis) does not have a claim in scientific research.
This is more broadly meant though. Usually you need to perform multiple studies and test multiple hypothesis to be able to critique a scientific argument and see whether the claims it makes and the predictions it makes hold up in scientific research.
<h3><u>Answer;</u></h3>
35.540 cubic inches
<h3><u>Explanation;</u></h3>
First we find the volume of the cylindrical container:
V = π(r^2)h
d = 3
r = 3/2 = 1.5
V = π(1.5^2)(8.5)
= 60.083 cubic inches
Then we find the volume of three tennis balls:
volume of one ball (sphere):
V = (4/3)π(r^3)
d = 2.5
r = 2.5/2 = 1.25
V = (4/3)π(1.25^3) = 8.181
volume of three spheres:
3 × V = 3 × 8.181
= 24.543 cubic inches
Then we get the difference to find the unused volume of the container:
60.083 - 24.543 = 35.540 cubic inches
