Space

Answer:

Center: (8, -4)

Radius: 2√3

General Formulas and Concepts:

Algebra I

  • Coordinates (x, y)

Pre-Calculus

Circle Center-Radius Equation: (x - h)² + (y - k)² = r²

  • (h, k) is center
  • r is radius

Step-by-step explanation:

Step 1: Define

Identify

(x - 8)² + (y + 4)² = 12

(h, k) = (8, -4)

r² = 12 → r = √12 = 2√3
