Write an equation of the circle with center (7,-9) and radius 6

The answer to your question is (x - 7) ² + (y + 9) ² = 36

Step-by-step explanation:

Data

Center = (7, - 9)

radius = 6

Process

1. - Write the standard form of a circle

(x - h) ² + (y - k) ² = r²

2. - Identify the values of h, k and r

h = 7 k = - 9 r = 6

3. - Substitution

(x - 7) ² + (y + 9) ² = 6²

4. - Simplification

(x - 7) ² + (y + 9) ² = 36
