Area of the square = (9 m)^2 = 81 m^2
The four circular sectors combine to form a circle with diameter 9 m, hence radius 4.5 m.
Area of the circle = π (4.5 m)^2 = 20.25π m^2
Then the area of the shaded region is
81 m^2 - 20.25π m^2 ≈ 17.4 m^2
You see 25 squares because length×height=area, and the area of a figure is how many of something is in it.
Get y by itself. Subtract 44 from both sides. Then you get the equation -4y=20x-44. Then divide by -4 to both sides to get y=-5x+11. Y=-5x+11 is correct. Hope this helps! ;)
The reciprocal of 2 5/7 is 7/19 because 2 5/7 as a mixed number is 19/7
