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???

Radius = 1/2 of Diameter

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.

### Acres in square or radius area would be better

difficult to know exactly what you are asking here
what is 16000 bbls--abbreviations do not known around the world so you need to be specific
next you are asking for a radius but include a height measurement.
an acre is a surface measurement but as soon as you give a 3rd dimension ( your height) it becomes a volume measurement or cubic ft/ yards or gallons
so post it all again and explain the end result that you want people to answer

### I need to know how much stone in tons I need to fill 8.5 acre at 1.5 ft depth

Stone is approximated at about 2700 lbs. per cu. yd.
An acre is 43560 sq. ft.
8.5 acres is 370260 sq. ft.
There 9 sq.ft. per sq. yd., thus there are 41140 sq. yds. in 8.5 acres.
A cubic yard is 3 feet by 3 feet by 3 feet (LxWxH).
Since you are only going to be at 1.5 feet, each square yard is equal to 1/2 cubic yard, so to figure the cubic yards divide sq.yds. by 2, thus you get 20570 cu. yds. of stone.

20570 x 2700 = 55539000 pounds. Divide by 2000 to get tons:
55539000/2000 = 27769.5 tons.

### How many cubic yards would it take to fill in. 20' x 2' diameter

Hi Paula:
A mathematical logic question.
You need to get all of the measurements in the same units.
- A cubic yard is 1 yard x 1 yard x 1 yard
- equals 3 ft x 3 ft x 3 ft
- equals 27 cubic feet,
so once you have the volume of the pipe in cubic feet, you divide by 27 to get the volume in cubic yards.
- Volume of a cylinder (the pipe) is the cross sectional area X length.
- Area equals Pi x r squared.
- equals 22/7 x 1 x 1
equals 3.14#####
times length (20)
equals 62.857### cubic feet volume
divide by 27 cubic feet
equals 2.328### cubic yards.

- The answer is always the easy part.
- what is important is knowing exactly what the question is, and
- determing what calculations are needed to get the answer.

Wasn't that better than if I'd just said 2 1/3 cubic yards?
Cheers

### What would the dimensions of an acre be in feet if all sides were equal?

Hi

A square-shaped acre would then be about 208.7 by 208.7 feet (because 208.7 x 208.7 = ~43,560, which is the defined area of an acre.)

Hope this helps.

### How many cubic feet is a 18 foot circle by 1 foot deep trying to find out how muck stone I will need for this project

First figure the area of the circle. The formula is

pi r squared, or

3.14 x (9x9).

Pi = approx 3.14.
Radius of 18' circle is 9'.
Area of circle is 254.34 square feet. To get cubic feet, multiply the area in feet by the depth in feet. In this case, since the depth is only one foot, the cubic feet will be 254.34 cubic feet (254.34 x 1)
