Answer:
r = 1.4
Step-by-step explanation:
c = Pi * D
So c = 8.8 = Pi * D
So divide both sides by Pi
so 8.8 / Pi = 2.801 = D
Radius is half the Dimeter so divide 2.801 by 2 = 1.4
Answer:
The independent variable is "x."
The dependent variable is "y."
Step-by-step explanation:
An independent variable is a variable that does not depend on an event. It is independent of another variable. It does not change as a result of another variable. It remains constant as it is controlled. It is used to measure the dependent variable.
A dependent variable varies. It depends on the independent variable for its outcome. It can yield various results depending on how the independent variable is changed. "y" in our example will change its value because of the value placed on "x." The dependent variable is the variable that is being measured or tested in an experiment. For example, the sales revenue of goods is a dependent variable of another independent variable like price and a constant (quantity).
