Answer:
81
Step-by-step explanation: 9 * 9 = -81 * -1 = 81
Answer:
We have been given a function and its graph.

The first point should be midline of the given function
We can see the coordinate of the midline which is (-3.14,2) will be the first point.
And second point should be maximum or minimum.
So, there is minimum according to the graph.
The minimum point will be at when 





So, the minimum point is:
Answer:
3 units
Step-by-step explanation:
The formula for the volume of the cone is given by


Substituting in above formula
![18\pi=\frac{1}{3} \pi*x^{2}*2x\\ \\ 54=2x^{3} \\ \\ x^{3} =27\\ \\ x=\sqrt[3]{27} \\ \\ x=3\ units](https://tex.z-dn.net/?f=18%5Cpi%3D%5Cfrac%7B1%7D%7B3%7D%20%5Cpi%2Ax%5E%7B2%7D%2A2x%5C%5C%20%5C%5C%2054%3D2x%5E%7B3%7D%20%5C%5C%20%5C%5C%20x%5E%7B3%7D%20%3D27%5C%5C%20%5C%5C%20x%3D%5Csqrt%5B3%5D%7B27%7D%20%5C%5C%20%5C%5C%20x%3D3%5C%20units)
Thus, the radius of the cone is 3 units.
