    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
