Answer:
Explanation:
The equation of the circle with centre: (8, -9) and radius of 19 is given as:
(x - 8)^2 + (y+9)^2 = 361.
The standard form for the equation of a circle is:
(x-h)^2 + (y-k)^2 = r^2. Where centre: (h, k) and radius: r.
Therefore, substituting given values, we'll have:
(x - 8)^2 + (y - (-9))^2 = 19^2, which is equal to
(x - 8)^2 + (y+9)^2 = 361.
