Answer:
1
Step-by-step explanation:
The cone is sliced by a plane, which produces a smaller cone on top. This cone is similar to the original cone. Therefore:
R / H = r / h
2 / 8 = r / 4
r = 1
Would that look like
? If so, you can multiply both sides by (4x-9) to cancel the 4x-9 on the bottom and get it onto the other side. It would look like this:
.
Distribute the 27 to the 4x and -9, which will get you this:
.
Then you want to add the 243 on both sides to isolate the x which should get you this:
.
Your next to final step is to divide both sides by 108 to leave the x alone. This will appear like this:
.
Your last step is to simplify the fraction or convert it into a decimal depending on which you prefer. If simplified, you should get
and for a decimal you will get ![x=13.67](https://tex.z-dn.net/?f=x%3D13.67)
