Answer: 8.69 (read explanation)
Step-by-step explanation:
If the one above it is only 8 and x is slightly better it would make much more sense for it to be 8.69..... try it, it sounds quit accurate.
We know that the volume is: V = 1 gallon = 231 in³
Also : r = 3 in.
The volume of a cylinder: V = r² π h
231 = 3³ · 3.14 · h
231 = 9 · 3.14 · h
231 = 28.26 h
h = 231 : 28.26
h = 8.17 ≈ 8 in
Answer: C) 8 in.
