A point in quadrant 4 could be (-4,-2)<span />
The complete formula for circumference is:

Since we know the circumference of the circle is 314 inches, we can then solve for d, the diameter:

Using 3.14 for pi, we get:

Then solve for d:

And now we know the diameter of the circle is 100 inches.
Step-by-step explanation:
x and y are roughly in a linear relationship.
when x increases by 2 units, then also y increases by more or less 2 units.
when x increases by 3 units, then also y increases by more or less 3 units.
it is not precise, but a good approximation model.
Answer:
Since them taken same time so the fraction is 1/1
Simple interest= prt
=806.68 (.0525)(1)
=42.35
Balance=investment + interest earned
806.68+42.35=$849.03
