Answer:
Step-by-step explanation:
1. To find the area of a semicircle the formula is
![A=\frac{\pi r^2}{2} \\=\frac{\pi 1^2}{2} \\=6.283m^2](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B%5Cpi%20r%5E2%7D%7B2%7D%20%5C%5C%3D%5Cfrac%7B%5Cpi%201%5E2%7D%7B2%7D%20%5C%5C%3D6.283m%5E2)
The square
![A=a^2=2^2=4m^2\\6.283+4=10.283m^2](https://tex.z-dn.net/?f=A%3Da%5E2%3D2%5E2%3D4m%5E2%5C%5C6.283%2B4%3D10.283m%5E2)
2. Triangle
![A=\frac{ab}{2} \\=\frac{6*2.5}{2} \\=7.5m^2\\7.5*2=15m^2](https://tex.z-dn.net/?f=A%3D%5Cfrac%7Bab%7D%7B2%7D%20%5C%5C%3D%5Cfrac%7B6%2A2.5%7D%7B2%7D%20%5C%5C%3D7.5m%5E2%5C%5C7.5%2A2%3D15m%5E2)
Rectangle
![A=wl=8*13=104m^2](https://tex.z-dn.net/?f=A%3Dwl%3D8%2A13%3D104m%5E2)
![104-15=89m^2](https://tex.z-dn.net/?f=104-15%3D89m%5E2)
3.
Semicircle
![A=\frac{\pi r^2}{2} \\=\frac{\pi 3^2}{2} \\\\=14.137m^2](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B%5Cpi%20r%5E2%7D%7B2%7D%20%5C%5C%3D%5Cfrac%7B%5Cpi%203%5E2%7D%7B2%7D%20%5C%5C%5C%5C%3D14.137m%5E2)
Square
![A=a^2=6^2=36](https://tex.z-dn.net/?f=A%3Da%5E2%3D6%5E2%3D36)
![36-14.137=21.863m^2](https://tex.z-dn.net/?f=36-14.137%3D21.863m%5E2)
Answer:
90
Step-by-step explanation:
The mode of the set is the number that occurs the most. In this case, 90 occurs more than any of the other terms. You can keep track using a tally chart:
80 |
82 |
90 ||
92 |
86 |
74 |
68 |
88 |
98 |
you would do PEMDAS
you do -3 times 4. then you do that and devide by -3.
