Answer:
![3) \: \: 113 {ft}^{2}](https://tex.z-dn.net/?f=3%29%20%5C%3A%20%20%5C%3A%20113%20%7Bft%7D%5E%7B2%7D%20)
![4) \: false](https://tex.z-dn.net/?f=4%29%20%5C%3A%20false)
![5) \: 70 {ft}^{2}](https://tex.z-dn.net/?f=5%29%20%5C%3A%2070%20%7Bft%7D%5E%7B2%7D%20)
Step-by-step explanation:
3) Area of a circle is
![\pi \times {r}^{2}](https://tex.z-dn.net/?f=%5Cpi%20%5Ctimes%20%20%7Br%7D%5E%7B2%7D%20)
Where r = 6
Thus,
![area = \frac{22}{7} \times {6}^{2}](https://tex.z-dn.net/?f=area%20%3D%20%20%20%5Cfrac%7B22%7D%7B7%7D%20%20%5Ctimes%20%20%7B6%7D%5E%7B2%7D)
![area = \frac{22}{7} \times 36](https://tex.z-dn.net/?f=area%20%3D%20%20%5Cfrac%7B22%7D%7B7%7D%20%20%5Ctimes%2036)
![area = 3.143 \times 36](https://tex.z-dn.net/?f=area%20%3D%203.143%20%5Ctimes%2036)
![area = 113 {ft}^{2} \: (nearest \: whole \: number)](https://tex.z-dn.net/?f=area%20%3D%20113%20%7Bft%7D%5E%7B2%7D%20%5C%3A%20%28nearest%20%5C%3A%20whole%20%5C%3A%20number%29)
4) False
Area of a circle is measured by the formula below:
![area = \pi \times {r}^{2}](https://tex.z-dn.net/?f=area%20%3D%20%5Cpi%20%5Ctimes%20%20%7Br%7D%5E%7B2%7D%20)
5) The formula for calculating the area of a rectangle is given thus:
![area \: of \: a \: rectangle = l \times w](https://tex.z-dn.net/?f=area%20%5C%3A%20of%20%5C%3A%20a%20%5C%3A%20rectangle%20%3D%20l%20%5Ctimes%20w)
Where, l = 10ft; w = 7ft
![area = 10ft \times 7ft = 70 {ft}^{2}](https://tex.z-dn.net/?f=area%20%3D%2010ft%20%5Ctimes%207ft%20%3D%2070%20%7Bft%7D%5E%7B2%7D%20)
