Answer :
Answer: The area of the region covered with small rocks is 49.76 ft²
Step-by-step explanation:
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
The radius of the garden is 4 ft
Therefore,
Area of garden = 3.14 × 4² = 50.24ft²
The length of each side of the square is 10ft.
Area of square = 10² = 100ft²
The area of the region covered with small rocks = Area of the square - area of the circular garden. It becomes
100 - 50.24 = 49.76 ft²
