Answer:

Step-by-step explanation:

Given: The center of the circle is (6,7) and the radius is 9.

To find: The standard equation for the circle.

Solution: The standard equation for the circle with center (a,b) and radius ris given as:

(x-a)^2+(y-b)^2=r^2

Now, the center is (6,7) and the radius is 9, thus the equation of circle is:

(x-(-6))^2+(y-7)^2=(9)^2

(x+6)^2+(y-7)^2=(9)^2

which is the required equation of circle with center as (6,7) and the radius is 9.

The standard equation for the circle centre can be written by using this formula: (x-h)² + (y -k)² = r² 

So, the equation in this case is: (x+6)² + (y-7)² = 81
