The answer would 2, since you cannot divide anything by 0 as it would be undefined. 2 is the only number that gives you this option
The answer for A is 2,026. I set a porportion up which is 77/x = 3.8/100
The answer to B is 26
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.
