Start by finding the area of one of the stools with this formula:
A=(3.14)(12)(12)
Then multiply that answer by five, since there are 5 stools.
Hope this helps :) good luck

For the a classmate ordered number it is not correct
Answer:
Step-by-step explanation:
Given function is,
![r(x)=\frac{3x^3-7}{x^2-6x+9}](https://tex.z-dn.net/?f=r%28x%29%3D%5Cfrac%7B3x%5E3-7%7D%7Bx%5E2-6x%2B9%7D)
For x = 0, substitute the value of x in the given function.
![r(0)=\frac{3(0)^3-7}{(0)^2-6(0)+9}](https://tex.z-dn.net/?f=r%280%29%3D%5Cfrac%7B3%280%29%5E3-7%7D%7B%280%29%5E2-6%280%29%2B9%7D)
![r(0)=\frac{-7}{9}](https://tex.z-dn.net/?f=r%280%29%3D%5Cfrac%7B-7%7D%7B9%7D)
For r = 3,
![r(3)=\frac{3(3)^3-7}{(3)^2-6(3)+9}](https://tex.z-dn.net/?f=r%283%29%3D%5Cfrac%7B3%283%29%5E3-7%7D%7B%283%29%5E2-6%283%29%2B9%7D)
![r(3)=\frac{81-7}{9-18+9}](https://tex.z-dn.net/?f=r%283%29%3D%5Cfrac%7B81-7%7D%7B9-18%2B9%7D)
![=\frac{74}{(9-18+9)}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B74%7D%7B%289-18%2B9%29%7D)
![=\frac{74}{0}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B74%7D%7B0%7D)
Function is undefined at x = 3.
For x = -3,
![r(-3)=\frac{3(-3)^3-7}{(-3)^2-6(-3)+9}](https://tex.z-dn.net/?f=r%28-3%29%3D%5Cfrac%7B3%28-3%29%5E3-7%7D%7B%28-3%29%5E2-6%28-3%29%2B9%7D)
![=\frac{-81-7}{9+18+9}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B-81-7%7D%7B9%2B18%2B9%7D)
![=\frac{-88}{36}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B-88%7D%7B36%7D)
