How many gallons of water does a 28 foot round 4ft deep above ground pool hold?

To calculate the number of gallons of water a 28 foot round, 4ft deep above ground pool holds, we can use the formula for the volume of a cylinder:

```

Volume = πr^2h

```

where:

- r is the radius of the pool (half the diameter)

- h is the height of the pool (the depth of the water)

In this case, the diameter is 28 feet, so the radius is 14 feet (28 / 2 = 14).

```

Volume = (3.14) * (14 ft)^2 * (4 ft)

Volume ≈ 1979.2 cubic feet

```

To convert cubic feet to gallons, we multiply the cubic footage by 7.481.

```

Volume ≈ 1979.2 cubic feet * 7.481 gal / cubic feet

Volume ≈ 14,790.79 gallons

```

Therefore, a 28 foot round, 4ft deep above ground pool holds approximately 14,790.79 gallons of water.
