<h3>How to identify the source and range of the signal?</h3>
Remember that a circle of radius R, centered at the point (a, b) is described by the equation:
In this case, we have the equation:
First, notice that 49 = 7², so we can rewrite:
Then, comparing this with the general circle equation, we can see that the center is at (5, -2) and the radius is R = 7.
Then the source is at (5, -2) and the range is 7 units.
