A circular garden with a radius of 4 ft is planted in the center of a 10-ft square. The part of the square that is NOT the garden is covered with small rocks. What is the area of the region covered with small rocks

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
