Can someone please help me out with this question. I'm in a timed test and I don't how to do this question. The question is on circle diameters, please help.

8121 because

130,000 divided by 16 is 8121

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
