Answer:
201.06 square feet.
Step-by-step explanation:
=> The diameter of a circle is equal twice its radius. So we divide the diameter by 2 to get its radius.
=> The area of any given circle is π times the square of the radius. The radius of this circle is equal to 8 feet.
=> Area of the circle = π × r² = 3.1415 × 8 feet = 201.056 square feet
