The answer to your question is (x - 7) ² + y² = 81
Step-by-step explanation:
Data
Center = (7, 0)
radius = 9
Process
To find the standard equation of a circle, just substitute the values of the center and the radius.
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
