Since 4 circles are circumscribed by a square, then the side length of the square is 8
So the area of the square is 8^2 = 64
The area of 4 squares is 4 * pi*2^2 = 16pi
So the answer will be 64 - 16pi
Answer:
b = 3 units
Step-by-step explanation:
Area of a parallelogram = base × height
Thus,
Area = 21 units²
base = b
height = 7
Plug in the value into the formula
Thus:
21 = b × 7
Divide both sides by 7
21/7 = b
3 = b
b = 3 units
Should be false because -7 x -7 is not -49 it is 49
