That question -- or ones nearly identical -- have been asked and answered here. Use the search tool at the upper right. Search on the following keywords: round pool 18 foot diameter Depth of the pool = 4 feet.Circumference of the pool = 18 feet. From the circumference we can find the radius of the pool.2(pi)(radius) = 18(pi) radius = 9Radius of the pool is (9/pi) feet.Volume of the pool = (pi)(radius)2(height) = (pi)(9/pi)24Volume of the pool = 324/pi cubic feet.

since c of the pool is 18 then 2pieR = 18 /2 pieR=9 /pie R=9/pie the radius is 9/pie

The answer to this question will require some simple dimensional analysis and geometry. Assuming that he pool is a round above ground pool, 18 feet in diameter and 48 inches deep you first need to calculate the area of the swimming pool in square inches and then multiply by the depth in inches to get the volume in cubic inches: The pool is an 18 foot diameter circle. The diameter in inches of the 18 foot pool is 216 inches (18 feet x 12 inches / foot) The area of a circle = pi (3.1415) x radius x radius The radius = 1/2 of the diameter The area of an 18 foot diameter pool in square inches is: 3.1415 * 108 inches * 108 inches = 36643.5 square inches The volume in cubic inches of an 18 foot diameter pool is: 36643.5 square inches x 48 inches = 1758890 cubic inches. There are 231 cubic inches in one gallon so the volume of an 18 foot diameter, 48 inch deep pool is: 1758890 / 231 = 7,614 gallons If it is a square or rectangular pool simply multiply the length x the width x the average depth.

mine is the same size as long as its 3 feet deep to 8 feet deep then the exactly 26730 gallons i figured that out today because we over shocked our pool by 4 times Assuming you are referring to an 18 foot by 3 foot (36 inches) circular pool, the formula would be PIE x radius x radius x depth = cubic feet, then cubic feet x gallons per cubic foot. So here is the answer.... 3.14 x 9 x 9 x 3 = 763.02 cubic feet, then 763.02 x 7.48 (gallons per cubic foot), = 5707.39 gallons. Diameter = total length across Radius = half of diameter Cubic foot = 1' x 1' x 1' 7.48 = gallons per cubic foot
