Answer:

  • 243 m²

Step-by-step explanation:

<u>Area of circle:</u>

  • A = πr²

<u>Circumference of circle:</u>

  • C = 2πr

<u>Given</u>

  • C = 55 m

<u>Find r using the second formula:</u>

  • 2πr = 55
  • 2*3.14r = 55
  • r = 55/6.28
  • r = 8.8 (rounded)

<u>Find area using the first formula:</u>

  • A = 3.14*8.8²
  • A = 243 m² (rounded)
