SOLUTION
We want to find the area of the circle in the picture given.
We have been given the formula as
![\begin{gathered} A=\pi r^2 \\ We\text{ are told to take }\pi\text{ as 3} \\ \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20A%3D%5Cpi%20r%5E2%20%5C%5C%20We%5Ctext%7B%20are%20told%20to%20take%20%7D%5Cpi%5Ctext%7B%20as%203%7D%20%5C%5C%20%20%5Cend%7Bgathered%7D)
From the circle, the radius r = 11 in.
The area of the circle becomes
![\begin{gathered} A=\pi r^2 \\ A=\pi\times r^2 \\ A=3\times11^2 \\ A=3\times11\times11 \\ A=363in^2 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20A%3D%5Cpi%20r%5E2%20%5C%5C%20A%3D%5Cpi%5Ctimes%20r%5E2%20%5C%5C%20A%3D3%5Ctimes11%5E2%20%5C%5C%20A%3D3%5Ctimes11%5Ctimes11%20%5C%5C%20A%3D363in%5E2%20%5Cend%7Bgathered%7D)
Hence the answer is 363 square-inches
Set as a proportion
16 = 12
------------------
5x+2 24
cross multiply
12(5x+2) = 16 * 24
60x +24 = 384
60x +24-24 = 384-24
60x =360
60x/60=360/60
x =6
To figure AB plug 6 into 5x+2
5x +2
5(6) + 2
30+2
32
AB = 32
$35,980 would be the correct answer.
