Answer:
The area which would be painted grey will be "47.7812 ft²".
Step-by-step explanation:
The given values are:
Radius of circle, r = 5.4 feet
Value of pi, π = 3.14
As we know,
Area of Semicircle = ![\frac{\pi r^2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cpi%20r%5E2%7D%7B2%7D)
On putting the values in the above formula, we get
= ![\frac{3.14\times (5.4)^{2}}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3.14%5Ctimes%20%285.4%29%5E%7B2%7D%7D%7B2%7D)
= ![\frac{3.14\times 29.26}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3.14%5Ctimes%2029.26%7D%7B2%7D)
= ![\frac{91.5624}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B91.5624%7D%7B2%7D)

Explanation:</h2>
Recall you need to write complete question in order to get exact answers. In this exercise, I'll assume that the complete question is:
<em>Makayla started a saving account. She starts the account with $20 and adds $80 at the end of each month. She will not remove any money from the account. How much money will she have at the end of month 11?</em>
<em />
So, she starts the account with $20, that is, this is a fixed amount of money and at the end of each month she adds 80$. So:
Let:
m: Represents the months.
s: Represents the amount of money that is saved.
We can write an equation:
![s=20+80m](https://tex.z-dn.net/?f=s%3D20%2B80m)
So, at the beginning of the process
so she have:
![s=20+80(0) \\ \\ s=20](https://tex.z-dn.net/?f=s%3D20%2B80%280%29%20%5C%5C%20%5C%5C%20s%3D20)
But at the end of month 11 she will have:
![s=20+80(11) \\ \\ s=20+80(11) \\ \\ \boxed{s=911}](https://tex.z-dn.net/?f=s%3D20%2B80%2811%29%20%5C%5C%20%5C%5C%20s%3D20%2B80%2811%29%20%5C%5C%20%5C%5C%20%5Cboxed%7Bs%3D911%7D)
So <em>at the end of month 11 she will have $911.</em>
