Answer:
D
Step-by-step explanation:
The formula for volume of cone is ![V=\frac{1}{3}\pi r^2 h](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2%20h)
Where
V is the volume
r is the radius of the circular base
h is the height of the cone
<em>In the diagram shown, we can clearly see that height is 12, radius is 9. We can simply plug them into the formula and get our exact answer (leaving pi as pi):</em>
<em>

<em>correct answer is D</em>
Solution:
we are given that
If G is the midpoint of FH, it mean that
![FG=GH](https://tex.z-dn.net/?f=FG%3DGH)
we are also given that
![FG=11x-7 ,GH= 3x+9](https://tex.z-dn.net/?f=FG%3D11x-7%20%2CGH%3D%203x%2B9)
So we can write
![11x-7=3x+9\\ \\ 11x-3x=7+9\\ \\ 8x=16\\ \\ x=2](https://tex.z-dn.net/?f=11x-7%3D3x%2B9%5C%5C%0A%5C%5C%0A11x-3x%3D7%2B9%5C%5C%0A%5C%5C%0A8x%3D16%5C%5C%0A%5C%5C%0Ax%3D2)
So ![FG=11x-7=11*\frac{1}{2}-7=11*2-7=15](https://tex.z-dn.net/?f=FG%3D11x-7%3D11%2A%5Cfrac%7B1%7D%7B2%7D-7%3D11%2A2-7%3D15)
Answer: A y= -4x + 2
Step-by-step explanation:
y= mx + b
when x is 0, y is 2 which you make the y intercept (b) 2
going from x=0 to x=1, the y coordinate moves down 4, so the slope would be -4
