Answer:

  • (x - 48)² + (y - 24)² = 64

Step-by-step explanation:

From the graph we see that

  • The diameter of the circle is: d = 16 mm
  • Then its radius is: r = 16 mm/ 2 = 8 mm
  • The center has x-coordinate: h = 40 + 8 = 48
  • Y-coordinate: k = 32 - 8 = 24

Use circle formula:

  • (x - h)² + (y - k)² = r²

Substitute values to get required equation:

  • (x - 48)² + (y - 24)² = 8²
  • (x - 48)² + (y - 24)² = 64
