how many gallons in a 30 ft. round x 54 inch deep pool?

Answer 1

I assume you mean 30 ft in diameter?

30 ft = 914 cm
54 in = 137 cm

volume = (pi)R^2 x height

3.14 x 457 x 457 x137 = 89,842,663 cm^3

89,842,663 ml = 89,842.7 liters

89,842.7 liters divided by 3.78 liters per gallon = 23,767.9 gallons

Answer 2

"a 30 ft. around" tells me that this would nicely be a pool that's 30 ft in circumference. My decision is unfair - persons answering have arbitrarily desperate which you meant something else. a pool with a 30 foot circumference that's fifty 4 inches deep has an entire quantity of 253.a hundred twenty five cubic ft, or 1893.fifty one gallons.

Answer 3

"a 30 ft. round" tells me that this is a pool that is 30 feet in circumference. My decision is arbitrary - other people answering have arbitrarily determined that you meant something else.

a pool with a 30 foot circumference that is 54 inches deep has a total volume of 253.125 cubic feet, or 1893.51 gallons.

Answer 4

1 cubic foot = 7.48 gallons
Volume of tank is Pi D = 22/7 x 30 x 4.5
= 660 x 4.5 / 7
= 2970 / 7 = 424.3 cubic feet
424.3 x 7.48 = 3173.8 gallons

Answer 5

30 foot dia = 15 foot circumferance x pi R squared = 706.86 square feet x 4.5 feet deep = 3180.87 cubic feet x 6.241 gallons per square foot = 20,424.25 Gallons! (u.k.)

Answer 6

Well, that's cubic feet, right?

4.5ft high, 30ft across, it's a cylinder, so volume is pi*r^2*h

(3.14159) * 15ft^2 * 4.5 ft = 3180 ft^3,
which is
23,788.05 gallons

Answer 7

approx. 12,000 gallons
