I feel like it's everything except for choices b and c. I hope this helps, but I would read them again.
Answer:
The height of the cone is ![h=9\ ft](https://tex.z-dn.net/?f=h%3D9%5C%20ft)
Step-by-step explanation:
we know that
The volume of a cone is equal to
![V=\frac{1}{3}\pi r^{2}h](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E%7B2%7Dh)
In this problem we have
![V=243\pi\ ft^{3}](https://tex.z-dn.net/?f=V%3D243%5Cpi%5C%20ft%5E%7B3%7D)
![r=h\ ft](https://tex.z-dn.net/?f=r%3Dh%5C%20ft)
substitute
![243\pi=\frac{1}{3}\pi (h^{2})h](https://tex.z-dn.net/?f=243%5Cpi%3D%5Cfrac%7B1%7D%7B3%7D%5Cpi%20%28h%5E%7B2%7D%29h)
simplify
![729=(h^{3})](https://tex.z-dn.net/?f=729%3D%28h%5E%7B3%7D%29)
![h=\sqrt[3]{729}\ ft](https://tex.z-dn.net/?f=h%3D%5Csqrt%5B3%5D%7B729%7D%5C%20ft)
![h=9\ ft](https://tex.z-dn.net/?f=h%3D9%5C%20ft)
Answers are as follows
B = 51.5
a = 34.6
c = 55.6
There isn't enough information because we don't know the amount Jill brought. We know the amounts Bill and Mike bought, but we know nothing about Jill.
Answer:
It looks like you wrote the equation in point-slope form perfectly!
But for part c, it seems as though x1 and y1 would represent parts of the midpoint formula. So, I would specify and say that they represent the midpoint, not just a point.
