Answer:
![Total = \$942](https://tex.z-dn.net/?f=Total%20%3D%20%5C%24942)
Step-by-step explanation:
Given
![A = (0,0)](https://tex.z-dn.net/?f=A%20%3D%20%280%2C0%29)
![C = (3,4)](https://tex.z-dn.net/?f=C%20%3D%20%283%2C4%29)

The cost of fencing the farm
First, calculate the radius of the farm.
The radius is represented with AC.
So, we have:
---- distance formula
So, we have:
![AC = \sqrt{(0 - 3)^2 + (0 - 4)^2}](https://tex.z-dn.net/?f=AC%20%3D%20%5Csqrt%7B%280%20-%203%29%5E2%20%2B%20%280%20-%204%29%5E2%7D)
![AC = \sqrt{(- 3)^2 + ( - 4)^2}](https://tex.z-dn.net/?f=AC%20%3D%20%5Csqrt%7B%28-%203%29%5E2%20%2B%20%28%20-%204%29%5E2%7D)
![AC = \sqrt{9+16}](https://tex.z-dn.net/?f=AC%20%3D%20%5Csqrt%7B9%2B16%7D)
![AC = \sqrt{25}](https://tex.z-dn.net/?f=AC%20%3D%20%5Csqrt%7B25%7D)
![AC = 5](https://tex.z-dn.net/?f=AC%20%3D%205)
Hence:
--- radius
Calculate the circumference of the circle
![C = 2\pi r](https://tex.z-dn.net/?f=C%20%3D%202%5Cpi%20r)
![C = 2 * 3.14 * 5](https://tex.z-dn.net/?f=C%20%3D%202%20%2A%203.14%20%2A%205)
![C = 31.4yd](https://tex.z-dn.net/?f=C%20%3D%2031.4yd)
If 1 yard costs $30, 31.4 yards will cost:
![Total = 31.4 * 30](https://tex.z-dn.net/?f=Total%20%3D%2031.4%20%2A%2030)
![Total = \$942](https://tex.z-dn.net/?f=Total%20%3D%20%5C%24942)
The fence is 26*7=182 square feet. 1 gallon is enough for 350 square feet and x for 182 square feet. => x=182/350=0.52 gallons. I hope I'm right.

I think it is C but it also could be B as well
