Area

154.89 acres = about 0.24 square miles.

15.81138832 = 250 square meters

Lateral area = 10*3 = 30 sq units

Total area = Lateral area + 2*Base area [top and bottom] = 30+2*7 = 44 sq units

A foot is 0.3048 meters. So that would give you 12.2 meters.

1 sq m = 1 million sq mm.

Solved with the help of the quadratic formula and Pythagoras' theorem.

Count the people, multiply by two. There is not other calculation possible from your question.

1 mile = 5280 ft.

The shape with minimal perimeter for a given area is a circle. Thus:

For an area of 21899 sq ft, the perimeter (circumference) is:

2 x {pi} x sqrt(area / {pi}) ~= 524.6ft

Meaning:

laps ~= 5280 ft / 524.6 ft

~= 10.1 laps. (just over 10 laps)

If the area is a square field, then, for an area of 21899 sq ft, the perimeter is:

4 x sqrt(area) ~= 591.9 ft

Meaning:

laps ~= 5280 ft / 591.9 ft

~= 8.9 laps (just under 9 laps)

If the area is a rectangular field, 1 ft wide and 21899 ft long (having an area of 21899 sq ft), its perimeter is:

2 x (length + width) = 43800 ft

Meaning:

laps = 5280 ft / 43800 ft

~= 0.12 laps (just over a tenth of a lap).

In fact any number of laps less than about 10.1 laps can be given as the answer as the perimeter can be made to be any length over about 524.6 ft by selecting the shape of the 21899 square feet area as appropriate.

If the perimeter of the shape is a fractal, it can have infinite length (even though it encloses 21899 square feet) and so the number of laps will be as near to nothing as makes no odds (ie effectively zero laps).

30' x 50' = 1,500 square ft = 0.03444 acre (rounded)

517 square miles = 1,339.024 km2

Answer: 14 mi² = 8,960 acres

The answer depends on what you mean by "sr ft".

Cubic ft and square feet cannot be compared. -They are totally different.

2,304 square feet (48 x 48 = 2,304)

9 yards = 8.2 meters.

If you mean as in the area of a circle that has a circumference of 518.519 feet

Then its radius is about 82.5 feet

The area of the circle: pi*82.5^2 = 21,382 square feet rounded

9,655,979,074 sq ft (rounded)

None.

A cubic foot is a measure of volume, a kilo is a measure of mass. The two measure different things and it makes no sense at all to try and convert from one to the other.
