Area

200 acres = 0.3125 mi²

45045 sq ft = 1.0340909.. acres

Couple of problems here . . .

1). The relative humidity of air depends in a really big way on the temperature of the air.

2). There's no such thing as a "cubic sq ft".

4 centimeters are in a Hershey's square.

9,364,602 sq feet (approx).

The unit of the these dimensions is missing.

One acre = 43,560 square feet.

a little less than 3 yards (2.8)

20' x 10' (200 square feet) = 22.22 square yards.

The formula for the area of a circle is:

V = pi times the radius squared. Pi equals (aproximately) 3.1415 so the area of a circle is 3.1415 X r X r and the atrea of a HALF circle would be half of that.

edit: how can a half-circle be 59 x 46 foot? it isn't a half-circle if it is uneven...

edit: you may be talking about an oval or elliptical shape. If it is a true ellipse with long radius = a and short radius = b then the area of a full ellipse = pi x a x b

If not a true ellipse your best bet would be to draw it to scale on graph paper. For example let each square on the graph paper be 1 ft. x 1 ft. After drawing as best you can then count the number of squares within your drawing. That number will be the number of sq. ft. This will be approximate because at the edges you will only have parts of squares inside your drawing so you have to estimate; .5 or .25 of a square etc. Then add these fractional parts to the total count of whole squares to get the final answer.

Assuming you mean 4" x 6" x 6' that would be one cubic foot volume

Or, if you meant 46' x 6' square feet, that would be 276 square feet

(3 x 39) + 2 = 119 feet.

Miles measures distance. Square miles measures area. Therefore, you can not compare the two. It is like comparing feet and cups.

There is no sensible answer to this question. A square foot is a measure of area, with dimensions [L2]. A foot is a measure of distance, with dimensions [L]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions without additional information.

Answer: 30 ft² = 2.78709 m²

Answer: 11.1 ft² = 1.03122 m²

Peru's area is 496,000 square miles (1,290,000 square kilometers).

Ten square miles is a square that is ten miles long and ten miles wide. If you walked across it in a straight line you would walk ten miles, if you walked the perimeter of it (all the way around all four sides) you would walk forty miles.

Sorry- disagree. 10 miles long and 10 miles wide is 100 square miles.

There is not enough information to tell. If you have the length of a wall, and the area being measured is rectangular, then you can find the length of the other wall by dividing the other wall's length into 570,025.

16,159 inches cubed is.
