Answer:
the calculation is correct but
what am I supposed to do with this
Answer:
Step-by-step explanation:
<u>Circumference formula</u>
<u>Solving for radius</u>
- 64 = 2*3.14r
- r = 64/2*3.14
- r = 10.19 ft
This picture is a square and inside the square we can see 4 piece of a circle.
The area of a piece of a circle=1/4 (area of a circle with radius = 9 m/2=4.5 m)
Therefore:
the area of a 4 piece of a circle=area of a circle with radius=4.5 m).
Area of the shaded region=area of the square -area of a circle.
1) we compute the area of the square:
area of a square=side²
Data:
side=9 cm
Area of this square=(9 m)²=81 m².
2) we compute the area of a circle with 4.5 m of radius.
area of a circle=πr²
area of this circle=π(4.5 m)²=20.25π m²
3) we calculate the area of the shaded region:
area of the shaded region=area of the square - area of the circle
area of the shaded region=81 m²-20.25π m²≈17.38 m²
Area= about 17.38 m²
Answer:
Final answer is ---> -4
