Find the area of the square:
Area = length x length
Area = 8 x 8 = 64 cm²
Find the radius:
Radius = Diameter ÷ 2
Radius = 8 ÷ 2 = 4 cm
Find the area of the two semicircle:
Area of the two semicircle = Area of 1 full circle
Area = πr²
Area = π(4)² = 50.29 cm²
Find area of the shaded parts:
Area of the shaded parts = Area of square - Area of the 2 semicircle
Area of the shaded part = 64 - 50.29 = 13.71 cm²
Answer: The area of the shaded parts is 13.71 cm²
