Volume = (4/3) x pi x r^3
With r = (10.8 / 2) = 5.4, r^3 = 157,464
Volume = 659,24928 cubic inches.

How much helium is needed to fill 20 12 inch balloons?
To find the volume of a sphere with a known diameter or radius (which is half the diameter), use the following formula: Asphere = 4/3 pi r3 pi = 3.14 and r = radius For a balloon with a diameter of 12 inches, the radius is 6 inches. Taking that information to the formula, you'll get 25.133 cubic inches (in3).

How many gallons of water in a 18x48 pool?
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.
Why there are gases in the balloon?
To inflate the balloon. Whether the gas is helium or just air from your lungs, gases are needed to inflate the balloon.
How many square inches in a 4 by 8 cylinder?
4 . 8 =32 A cylinder is round and its circular area is dependant on one dimension only - its diameter or radius. If the diameter is 4 inches then the area is Pi/4 x 42 = 4*Pi If the diameter is 8 inches then the area is Pi/4 x 82 = 16*Pi If you needed the surface area and the diameter was 4 inches and the height was 8 inches, then the surface area would be (circumference) x height = (Pi x 4) x 8 = 32*Pi square inches. Of course Pi = 3.14159 to the nearest 5th decimal.
