Answer:
I wish I could help but I forgot how to do this, sorry. :(
1. x=24
2. r=9
3. w=33
4. n=19
Well, to solve, you would subtract 8 from both sides, which means x would end up equaling 32.
X=32
Volume of a cylinder = π · radius(r)² · height(h)
Since you didn't provide the radius or the height, I am unable to provide a solution to this problem but hopefully you can solve it on your own now that you have the formula.
