We are required to find the diameter of the circle based on given circumference.
We know that:

rounded to two decimal places
Therefore, the diameter of the circle with circumference 15.70 is 5
So than there are
1x -5y =15
-1x +5y = -15
--------------------assuming term by term we get
0 0 = 0
so from what result that this system has infinitely many solutions
hope helped
