Answer:

Standard Equation:

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

General Equation:

x^2 + y^2 - 4x - 18y + 76 = 0

Step-by-step explanation:

(x-h) ^2 + (y-k) ^2 = r^2

(x-2)^2 + (y-9)^2 = (3)^2

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

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

(x^2 - 4x + 4) + (y^2 - 18y + 81) = 9

Ax^2 + By^2 + Cx + Dy + E = 0

(x^2 - 4x + 4) + (y^2 - 18y + 81) - 9 = 0

x^2 + y^2 - 4x - 18y + 4 + 81 - 9 = 0

x^2 + y^2 - 4x - 18y + 76 = 0
