You could have looked this up as easily as posting it. Cubic feet = L x W x H = 4800 cubic feet of water. One cubic foot = 7.48052 gallons. Therefore 4800 x 7.48052 = 35906.496 gallons
There is NO way to calculate this without knowing how deep the pool is filled!
It is 30.6 cubic feet = 190.3 Imperial gallons.
There are 13,536 gallons in a 24 foot diameter pool that has 4 feet of water. Not true for a pool that is 4 feet in height. This would hold less than 4 feet of water.
pie times 12 squared time 5 divided by 0.133680556 cubic feet per gallon Answer is 53,283 Gallons
A 20 foot round pool has a radius of 3.2 feet. So the pool has a volume of pi*r2*h = 101.86 cubic ft approx.
They are to inform the swimmer how deep the water is. It is always good to know the depth for safety reasons. It is not a good idea to dive into a 3 foot deep pool.

WolframAlpha, a new search engine gives a UK gallon of water at 0.1337 cu.ft so your pool should take 6,462 gallon to fill, give or take a cupful. Check it out!
It matters how deep you go in the water as in the sea water I only go up to my waist and i'm 5 foot 7

75 x 30 x 5 = 11,250 cubic foot 1 cubic foot = 7.48 Gallon (US) 1 cubic foot = 6.23 Gallon (Imperial) 11,250 x 7.48 = 84,150 Gallon (US) 11,250 x 6.23 = 70,087.5 Gallon (Imperial)

21 foot what? Radius, diameter or circimference? Presumably 4 feet deep?
You don't say how deep the pool is and whether you're using US or UK gallons. However... One cubic foot contains approximately 7.5 US gallons, or 6.25 UK gallons, so if you multiply 10 x 3 x (pool depth) by either of the above you will get the approximate gallon count.
a gallon or so
question is meaningless. gallon is a unit of volume, sq ft is a unit of area. the above is a horrible answer. simply put your question was miss worded. i believe you meant cubic foot (not square foot). the answer is 7.481 gallons in a cubic foot
