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 mylar balloons can a 135 lb helium tank fill?
When filled, party balloons generally have a diameter of 10 to 12 inches. The volume of each size is as follows:10 inch balloon = 523 cubic inches (rounded to the nearest whole number)12 inch balloon = 904 cubic inches (rounded to the nearest whole number) 523 cubic inches = 0.30 cubic feet (rounded to the nearest hundredth)904 cubic inches = 0.52 cubic feet (rounded to the nearest hundredth) Therefore, a 9 cubic foot tank would fill between 17 and 30 balloons of this size.
