How many gallons of water are in a 24 foot round pool at 4 deep?

$$V=\pi r^2 h$$

- V is the volume in cubic units (gallons)

- r is the radius in units (feet)

- h is the height in units (feet)

$$V=\pi(12\text{ ft})^2(4\text{ ft})$$

$$V=(144\pi \text{ ft}^2)(4\text{ ft})$$

$$V=576\pi \text{ ft}^3$$

Converting cubic feet to gallons by multiplying the cubic feet by 7.48 gives:

$$(576\pi \text{ ft}^3)(7.48$$

5,286.99 gallons of water to fill a 24-foot round pool that is 4 feet deep.
