Answer:
Sandy needs
of carpet to build a scratching post for her cats
Step-by-step explanation:
Sandy needs to calculate the surface area of the cylinder
The surface area of the cylinder is equal to
![SA=2\pi r^{2}+2\pi r(h)](https://tex.z-dn.net/?f=SA%3D2%5Cpi%20r%5E%7B2%7D%2B2%5Cpi%20r%28h%29)
we have
----> the radius is half the diameter
![h=4\ ft](https://tex.z-dn.net/?f=h%3D4%5C%20ft)
assume
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
substitute the values
![SA=2(3.14)(0.5)^{2}+2(3.14)(0.5)(4)](https://tex.z-dn.net/?f=SA%3D2%283.14%29%280.5%29%5E%7B2%7D%2B2%283.14%29%280.5%29%284%29)
![SA=14.13\ ft^{2}](https://tex.z-dn.net/?f=SA%3D14.13%5C%20ft%5E%7B2%7D)

Answer:
The optimal price should be $10 which will result in maximum revenue.
Step-by-step explanation:
y = [5+ 0.5x] [ 300 - 30x]
y = 1500 - 150x + 150x - 15x^2
y = 1500 - 15x^2
x^2 = 1500 /15
x = ![\sqrt{100}](https://tex.z-dn.net/?f=%5Csqrt%7B100%7D)
x = 10
We are given equation V = r²h.
Let us break it into parts to get the correct variation.
V = r²h could be written first V= r² × h.
And we could break it in two different proportions:
V ∝ r² can be read as V is directly proportional to r².
V ∝ h can be read as V is directly proportional to h .
Non of the variable r² or h in denominator.
<em>When we have any variable in denominator, it's an inverse variation and if we don't have any variable in denominator, it would be a direct variation.</em>
<h3>Therefore, we can say V = r²h is a direct variation.</h3>
