Assuming it is 9 INCHES deep, Vol = pi*r2*h = pi*(d2/4)*h = 19113 cubic inches (approx).
In cubic inches it is: pi*4.5*4.5*24 = 486*pi or about 1527 rounded
cylinder 18 feet diameter x 1.5 feet deep volume = 381 cubic feet
About 8.5 (Pi*(6/12)^2*290)/27
A hole 40 inches deep by 12 inches wide has a volume of: 2.62 cubic feet.
The volume of an area 24 feet round and 45 inches deep is: 1,700 cubic feet.

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.
29.45 cubic feet or 183.45 US gallons.
Does "15 foot round" refer to Perimeter, Diameter or Radius.
