Did ancient mathematicians use a ruler to determine the values of sine and cosine in a circle? No answer needed, just take points.

No, they did not! Thought i would answer since i've just been thanking and acting like a stalker..

But still... thank you!

i think the correct option is the second option.

$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
