Assuming the average composition of air weighs approximately 0.0807 lbs per cubic foot, what is the weight of air in a giant balloon with a diameter of 6 feet?
Assuming the balloon is spherical in this occasion :
3^2 x pi = 23.37 (ish)
23.37 x 6 = 140.22 (ish)
140.22 x 0.0807 = 11.315754 (ish)
(ish) is explained by my use of pi
And I was also unsure of the unit the diameter was measured
