shall assume the 18ft measurement is the diameter, not radius.
18ft = 5.486m = diameter
52in = 1.321m = depth
pi x radius(squared) = area of the circle
pi x 2.243(squared) = 15.8055 meters squared
area x depth = volume in meters cubed
15.8055 x 1.321 = 20.879 meters cubed
1 meter cubed = 1000L
20.879 meters cubed = 20879L
20879L is:
5515.648 US Gallons
4592.738 UK Gallons
Cannot be answered with only these measurements. For a rectangular pool, the length, width and depth are needed. For a round pool, the diameter and depth are needed.
44.883 gallons for each inch of depth. (rounded) 538.6 gallons for each foot of depth. (rounded)
18 feet 6 inches=222 inches
It is unlikely that the pool is 48 feet deep but there is no indication as to what units the depth is measured in. Consequently it is not possible to answer the question.
18 x 33 x 5 = 2970 cubic feet 1 cubic foot = 7.48052 gallons therefore, your pool is 22217.1 gallons
A pool this size can hold up to about 5,250 gallons of water.

Approximately 8,887 gallons.
Carefully ..... and as level as possible.

First find the area of the cylinder in sqft. V= (3.14) x .5' x 40' = 62.8 sqft 1 sqft holds 7.48 gallons 62.8 x 7.48 = 469.74 Gallons
It's a perfect circle? Is it 18ft across or 18ft around the edge? If it is 18ft across then the radius is 9 feet and the volume (amount of water needed) is going to be (pi)x (r squared)= 81pi which is about 254.469 square feet x 4 feet in height = 1018 cubic feet. A cubic foot is about 7.5 gallons so you need 7634 gallons of water to fill your pool. If it is 18ft around the edge then 18ft=2(pi)(r) 9=(pi)(r) r= 2.86ft (which would mean that your pool is about 5.75 ft across) then we use the same volume formula from above Volume = Area of the circle(that forms the bottom) x Height. Area of the Circle is pi(r squared) where r is half of the distance across the pool. Called the radius. r in this case is 2.86 so (2.86 squared) x pi = 25.78. Multiply by the height (4ft) gets you 103.13 cubic feet. 1 cubic foot is about 7.5 gallons so multiply by 7.5 and you get 773.5 gallons to fill your pool. You figure it out by getting the volume of the cylinder (pool's shape) which is the area of the cirle on the bottom x the height and then multiplying that answer by the conversion factor for cubic feet to gallons. Hope this helps!

Average Depth = Deep End (feet) + Shallow End (feet) divide by 2 Rectangular / Square Pool: Length (feet) x Width (feet) x Average Depth x 7.5 = Total gallons Circular Pool: Diameter x 2 x Average Depth x 7.5 = Total gallons Oval Pool: Max Length (feet) x Max Width (feet) x Average Depth x 7.5 = Total gallons Kidney Shaped Pool: Width of Shallow End (feet) + Width of Deep End (feet) x Length of Pool x 0.45 x Average Depth x 7.5 = Total gallons Free Form Pool: Max Length (feet) x Max Width (feet) x Average Depth x 7.5 = Total gallons
The formula for the volume of a cylinder is Volume = height * pi * radius squared. That gives the volume in cubic feet, cubic meters or whatever your unit of measure might be. Convert from cubic ft to gallons using: 1 cubic foot = 7.480 519 481 gallon [US, liquid]
