Answer:
Area of remaining board is 13.728 feet²
Step-by-step explanation:
Given; Square side length = 8 feet
Therefore, the diameter of the cut out circle = 8 feet, then Radius = 4 feet
The approximate area, in square feet, of the remaining board will be the are of the square minus the ares of the cut out circle.
Area of the square = S²
= (8 feet)²
= 64 feet²
Area of the cut circle = π(4 feet)²
= 3.142 x 16 feet²
= 50.272 feet²
Area of remaining board = Area of the square - Area of the cut circle
Area of remaining board = 64 feet² - 50.272 feet²
Area of remaining board = 13.728 feet²
