In order to solve for this, we need to find the volumes of both the cylinder and cone described.
In order to find the area of the cylinder:
We use the equation V=

So, V=

The volume of the cylinder is therefore approximately <span>1809.56

For the cone:
V=

So, V=

Thus, the volume of the cone is 113.1

We add these volumes together to derive the solution, which is 1922.66

17 = -13 - 8x .....add 13 to both sides
13 + 17 = -8x
30 = -8x...now divide both sides by -8
-30/8 = x...reduce
- 15/4 or -3 3/4 = x <===
Answer:171x+8
Step-by-step explanation:
3x^3+12x^2x+8
=27x+144x+8
=171x+8
I believe it would be 12 because 9 min divided by .75 a rotation gets 12 rotations
