Answer:
Step-by-step explanation:
Let's x be the length of the side that is NOT the same as the side along the river (or in opposite). From the fencing perimeter of 2200ft we can calculate the other side y of the rectangular:
y = 2200 - 2x
The area A of the pen would be the product of the 2 sides
This simplified is 126x so that is equivalent to this expression
The period of a sinusoid

is

, so any range such that

will give two complete periods.

We know that
circumference=pi*D
where
D is the diameter
D=91 cm
so
pi-----> is the value of the calculator------> 3.1415926535897932
circumference=pi*91------> 285.88 cm------> 285.9 cm
the answer is
285.9 cm
