Greeley [361]

Answer:

The answer to your question is   (x - 7)² + y² = 81

Step-by-step explanation:

Data

Standar equation of a circle

                     (x - h)²  +  (y - k)² = r²

-Identify the values of h and k

                     h = 7    k = 0   and r = 9

-Substitution

                    (x - 7)² + (y - 0)² = 9²

-Simplification

                  (x - 7)² + y² = 81
