Answer: the answer is 21.5 inches squared
Explanation:
Area of the square: 10x10 which is 100
Then area of the circle: Pi x radius squared
So Pi x 5 squared which is 78.54 (to nearest 2dp)
Then finally, subtract to get the shaded region
So 100-78.54= 21.46
However they want this to the nearest tenth so it would be 21.5
