Answer:
The answer is 0.045 kg/cm³
Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass of cylinder = 14 kg
Volume of a cylinder = πr²h
where
r is the radius
h is the height
[tex]radius = \frac{diameter}{2} \\ [/tex]
From the question
h = 25 cm
[tex]r = \frac{4}{2} = 2 \: \: \: cm[/tex]
The volume of the cylinder is
[tex]V = {2}^{2} (25)\pi \\ = 4 \times 25\pi \\ = 100\pi \\ = 314.159265...[/tex]
We have
volume = 314.159 cm³
The density of the cylinder is
[tex]density = \frac{14}{314.159} \\ = 0.044563421...[/tex]
We have the final answer as
0.045 kg/cm³
Hope this helps you
