Answer:

383 cm²

Step-by-step explanation:

⇒ Area of the figure = Area of the circle - Area of the 5-sided polygon (pentagon)

Finding P (Perimeter of the Pentagon)

  • P = 5(21.2)
  • P = 106 cm

Finding Area

  • A = πr² - 1/2Pa
  • A = 3.14 x (19.8)² - 1/2 x 106 x 16
  • A = 3.14 x 392.04 - 53 x 16
  • A = 1231.0056 - 848
  • A = 383.0056 ≅ 383 cm²
