Find the area of the square:
Area of a square = Length x Length
Area = 63 x 63 = 3969 cm²
Find the radius:
Radius = Diameter ÷ 2
Radius = 63 ÷ 2 = 31.5 cm
Find the area of the two semicircles:
Area of 2 semicircles = Area of 1 circle
Area of a circle = πr²
Area of a circle = π(31.5)² = 3118.5 cm²
Find the area of the square not covered by the 2 semicircles:
*See attachment
Area = 3969 - 3118.5 = 850.5 cm²
Find the total area not shaded:
*See attachment
Area not shaded = 850.5 x 2 = 1701 cm²
Find the area of the shaded part:
Area = 3969 - 1701 = 2268 cm²
Answer: 2268 cm²

but their is empty space between the semi circle ryt
That is why I did it twice. First time for the first set of empty space (See attachment 1) And then i multiply it by 2 (because there is another similar empty space of the other side as well)
Note that there is 2 attachments here. One shows the first set of empty space, the the other attachment, the other set.
thank you for you explanation :)
