Volume of a cylinder = (pi) x R2 x H
R = 1/2 diameter = 9-ft
Volume = (pi) x (9)2 x (4) = 1,017.876 cubic feet = 7,614.24 gallons (rounded)
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
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
36 feet.
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.
9 feet in toward the exact center.
A pool this size can hold up to about 5,250 gallons of water.
Circumference of a circle = 2*pi*radius or diameter*pi
Approximately 8,887 gallons.
44.883 gallons for each inch of depth. (rounded) 538.6 gallons for each foot of depth. (rounded)
A linear foot is the same as a foot. So, an 18-foot diameter circle would measure 18 linear feet in diameter!
18 x 33 x 5 = 2970 cubic feet 1 cubic foot = 7.48052 gallons therefore, your pool is 22217.1 gallons
Circumference = 2(pi)r if diameter = 18ft then the radius is 9ft, so: Circumference = 2(pi)9 = 56.54ft =] -ray
