Oh wow, lots of math going on here...

There are 4840 square yards in an acre and 9 square feet in a square yard (4840 x 9 = 43,560).

An acre is an old timers measurement used in agriculture...
it was 4 poles wide and 40 poles long. A pole is equivalent to sixteen and a half feet. So back then, an acre was a piece of farming land 660 feet long (220 yards or one eighth of a mile) and 66 feet wide (22 yards or one eightieth of a mile).

Acre is a measure of area, which would be square feet.

Feet are a measure of distance.

The best you could do is something like this:
An acre is 43, 560 square feet.
Draw/imagine a square or a rectangle that would cover that much area.

If it is a square, it would be (approximately) 208.7 feet on each side.

Its perimeter (the distance around it if you walk an imaginary fence around you acre-sized plot) would be 834.8 feet.

Trying to to figure out an acre of 'Circle' - hmmmmm???

sorry, just can't wrap my head around this to come up with the correct equation.
maybe we can get lucky with some other brainiac taking what I did provide and come up with a solution for you?

Square - It would be 208.7 feet across if you walk across it, and the same if you walk the other way across it.

Come on princess. Use the formula for the area of a circle: Area=PI*D*D/4
where PI can be entered using a key on the calculator, and D is the diameter.
Area =100*Pi cm^2 or about 314.159 cm^2
