The equation of the given circle is
Step-by-step explanation:
Step 1:
The equation of a circle with its center at (h, k) and a radius of r is given by
The h value is the x coordinate and the k value is the y coordinates, so (h, k) is (6, -9).
The radius is given as 10 so and
Step 2:
By substituting the values we know, we get
So the equation of the given circle is
To solve this, we have to simplify these numbers by adding like terms.
Next, we factor our expression. To do so, we look for the greatest common factor of 42 and 14, which is 14. We know that because 42 divided by 14 is 3.
