Question

(x - 9)2 + (y - 4)2 = 400 Center: Radius:

Answer 1

Answer:

Center: (9, 4)

Radius: 20

Explanation:

(x - 9)² + (y - 4)² = 400

The Circle Formula:

(x - h)² + (y - k)² = r²

where (h, k) is center points, r is radius

Rewrite the equation:

(x - 9)² + (y - 4)² = 20²

Identify following:

h = 9, k = 4, radius = 20

Answer 2

Answer:

Step-by-step explanation:

Center: (9, 4)

Radius: √400 = 20
