Imagine a rectangular playground that measures 40 meters in length and 30 meters in width. In the center of this playground, there is a circular sandbox with a diameter of 10 meters. Your task is to determine the area of the playground that is not covered by the sandbox.
To solve this problem, you will need to calculate the area of both the rectangle and the circle. The area of a rectangle can be found using the formula:
Area of Rectangle = Length × Width
And the area of a circle can be determined by the formula:
Area of Circle = π × (Radius)^2
Where the radius is half of the diameter.
