independent variables are things that YOU change to get a result from the dependent variables. ususally you can measure the independent variables directly

so height is something that you can change to get different volumes. it is independent

constant variables do not change - they are "constant"

4 is a constant variable because no matter what value of s you put in, it will still be 4

A is dependent on the radius .. .it is dependent .. you cannot really directly measure area, but you can measure length (radius)

r is independent in the last one for the same reason as the first one...

A variable Is a component of a situation or equation.

Look at the basis of the descriptions:

INDEPENDENT , and independent person is someone that is on their own and doesn't care what anyone else does or says. so an independent variable is a specific value that is stated and doesn't change unless you are told it changes.

DEPENDENT, the opposite of independent, a dependent person can only make their decisions based on others' actions and decisions, thus a dependent variable depends on something else to determine its value.

CONSTANT, something that never changes so a constant variable will never change even when all other components of an equation do

So for the problems (I'm doing your homework aren't I?)

h is an independent variable. The length and Width of a cube do not effect its Height, however the H changes from cube to cube.

4 is a constant variable, no matter what happens, that number will always be 4

A is dependent, the Area changes as the length of the radius (r) changes. (on a side note, pi is a constant variable it is always 3.1415...)

r is independent, the rate in the simple interest equation changes, but it does not rely on the payment or time.

does that help?

Independent variables are variables that do not depend on anything (like time. Time passes no matter what. No matter if a car goes faster or slower, it still passes). Dependent variables depend on the independent variable (like the speed of light).

The dependent variables should be graped on the y axis and the independent variables on the x axis.
