I need an approx. volume of a pond please.?

If it's an ellipse the area is pi*r1*r2, r1 and r2 being the semimajor and semiminor axes. This is 3.14*25*9 ~= 705 sq. ft. You'll have to estimate the average depth. If it's 4 feet you have 4*705 ~= 2820 cu ft. There are ~7.5 gallons in a cu ft, so that's 7.5*2820 ~= 21200 gallons.

once you have the dimensions for the aquarium.\nyou'll want to find the volume of it.\n\nVolume = length x width x heigth\n\nconvert the volume into ounces (can be done using any website that does conversions)\n\nAnd divide that by 8...and you have your answer

3.2 in an acre I think\n\nwill modify later if I find otherwise

You can do this with some math.  I'm assuming 12 feet is the diameter.  So the radius would be half that, or 6 feet.  2.5 feet (30 inches) is the height.\n\nThe volume of a cylinder is the area of the circle, times the height.\n\nV = pi r^2 h\n\nSo the volume is 3.14159 x 36 x 2.5\nThis is approximately 282.743339 cubic feet.\n\nOne cubic foot holds 7.48051945 US gallons, so you multiply 282.74 x 7.48 to get around 2,115 gallons.\n\nIncidentally, a gallon of water weighs 8.34 lbs, so you are talking about 17,639 lbs or nearly 9 tons of water!!!  Be sure the sides and the base are well constructed.

This is not tricky at all. The volume is 1-1/2 cylinders of "height" 50,000 meters and radius 4 meters.\n\nThe formula for the volume of a cylinder is\n\nV = pi * r^2 * h

Depends on the height.\n\nV=pi*r^2*h\n\n1 ft^3 = 7.48 gallons (U.S.)

You could place a vertical rod in the pond (on a stand or stuck in the mud?) and start the experiment when the rod is dry.  After you create the wave and the surface returns to rest, measure the height of the wave on the rod.  This will be the maximum height of the waves at the given point and will depend on the location of the disturbance (radiates outwards like a bullseye?).  Also, there should be nothing near the rod to magnify the wave (including shore effect or irregular bottom?).  Applying chalk to the rod (especially blue chalk?) may make the wetted height more visible and resist drying too fast.  Including a scale on the rod may allow you to read the wetted height above calm surface easier, especially using binoculars.  The trough should approximately equal the wave height.  Good luck.

in a pond! just kidding i live in oregon and know nothing about where you are but hey good luck

Department of wildlife and fisheries is the way to go, but to really get a fell for the ponds stop the small bait shops in your area, ask the old guy behind the counter he will give you the best info. Seriously I grew up outside Boston and fished the South shore for years but when I moved out to central mass, I had no idea where to begin. I stopped at a little shop out on 122 I believe. And actually talked to the guy who wrote for the Telegram. Some of the best info I have received.

Let the height be h (inches), radius r.\n\nNow by proportion, h = 5r at every level.\n\nHence volume is given by\n\nV = (1/3)pi*r^2*h which is\n       (5/3)*pi*r^3\n\n"Rate at which water is drained" means find dV/dt\n\ndV/dt = 5*pi*r^2*(dr/dt),\n\nand dr/dt = (1/5)*(dh/dt)\n               = -2/5\n\nYou can finish from there.

MOVE YOUR POOL TO WHERE FROGS DON'T FREQUENT.\n\nSUCH AS THE TUNDRA.

it would be 461/2 gallons

Multiply cubic feet by 7.481 to get gallons.
