By using the distance formula. We calculate the difference of the like coordinates (e.g longitude1-longitude2 or latitude1-latitude2 etc) then add the "squares" of the differences. And finally taking the square root of the answer.
A reasonable estimate will give an indication of the order of magnitude of the number. The order of magnitude is determined by the decimal point and so knowing the order can help in placing it.
Knowing the divisibility rules will help you by being able to recognize if a number has factors (other than one and itself) which are covered by the rules. This will save actually having to start doing divisions.
No possible to determine without knowing what you are trying to measure. You need to be able to calculate the density of the liquid (e.g. water vs mercury).
It is impossible to answer the question without knowing the shape of the base, which will determine how many sloped triangles there are.
i think that the range and the domain of a parabola is the coordinates of the vertex

It will be impossible to answer this question accurately without knowing what the questioner wants to determine.
Knowing the properties of fuel is very helpful. For eg, if we know its burning temperature and amount of calories produced, we can determine its efficiency to be used as a fuel. also by knowing the properties of viscosity we can determine its rate of flow, how to efficiently use it for the various purposes. Properties help to determine the best use of the liquid and thus increasing efficiency and productivity.
yes

We cannot determine the circumference of a tank by knowing its height. Its like measuring the weight of an object by knowing its length.
No way to determine without knowing manufacturer and model of rifle.
temperature.
You can't, although if there is also enough moisture, you can determine what seed might germinate.
