How many gallons of water in a round pool 10 ft and 30 deep bestway fast set pool?

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

where:

* $$V$$ is the volume in cubic units

* $$r$$ is the radius of the cylinder in units

* $$h$$ is the height of the cylinder in units

In this case, the pool has a radius of 10 feet and a height of 3 feet. So, the volume of the pool is:

$$V = \pi (5 ft)^2 (3 ft) \approx 471.24 ft^3$$

To convert cubic feet to gallons, we need to multiply by 7.48. So, the pool holds:

$$471.24 ft^3 \times 7.48 \approx 3,528 gallons of water$$

Therefore, the round pool 10 feet by 30 feet deep Bestway Fast Set pool holds approximately 3,528 gallons of water.
