To calculate: The point
The point is located at inside the crater.
Given information: Three points on the edge of the circular crater represented by the coordinates
Calculation:
Let
The points
Applying the binomial formula, the system can be written in the following way:
Subtracting the second equation from the first one
Subtracting the second equation from the third one
Now have a
From the second equation
Substituting this into the first one,
Substituting this into the expression for
The centre is
The point
That means that the distance of
Since
