The answer is 40, I just took the test.

Answer:

[tex]40\ m^{3}[/tex]

Step-by-step explanation:

we know that

If two figures are similar then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z-----> scale factor

x-----> the volume of the dilated cone

y-----> the volume of the original cone

[tex]z^{3}=\frac{x}{y}[/tex]

In this problem we have

[tex]z=1/5[/tex]

[tex]y=5,000\ m^{3}[/tex]

substitute and solve for x

[tex](1/5)^{3}=\frac{x}{5,000}[/tex]

[tex](1/125)=\frac{x}{5,000}[/tex]

[tex]x=5,000/125=40\ m^{3}[/tex]
