Question

(x - 9)2 + (y - 4)2 = 400

Center:

Radius:

Answer 1

Center: (9, 4)

Radius: 20

Step-by-step 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
