Answer: The equation of the circle is

Step-by-step explanation: We are given to write the equation of the circle with radius √13 units and center at the point (-9.3, 4.1).
We know that
the standard equation of a circle with radius r units and center at the point (h, k) is given by

In the given circle,
radius, r = √13 units and center, (h, k) = (-9.3, 4.1).
Therefore, the equation of the circle will be

Thus, the equation of the circle is

Is this all there is to the question????
31.4% should be divided by 100 to get decimal
31.4/100
0.314
The square root of 81 is 9 because 9x9=81 so thats definitely an integer its a rational number.
