fifty-six The circumference of an 18-foot diameter circular swimming pool is: 56.55 feet
If that is 4 feet tall and 18 inches in diameter, it would be 16.83 gallons.
Cannot be answered with only these measurements. You need to specify what shape the pool is. Also, for a rectangular pool, the length, width and depth are needed. For a round pool, the diameter and depth are needed.
Circumference of any circle = 2*pi*radius or diameter*pi

To fill a round pool that is 18 feet in diameter and 5 feet deep, you would need approximately 14 cubic yards of earth.

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.

Circumference = 18 feet.Depth = not known.
Circumference of any circle = 2*pi*radius or diameter*pi
Depending on how full you are getting the pool (vinyl pools typically go to 80%) you are looking at 3,700 gallons for an 18 foot by 36 inch pool.

For round pools. All calculations using feet not inches. Multiply pool diameter x pool diameter x pool depth x 5.9 = gallons
