Question 1153519:
A spherical weather balloon needs to hold at least 112

cubic feet of helium to be buoyant enough to lift the meteorological instruments.
Will a helium filled balloon with a diameter of 6 feet stay​ aloft?

volume of a sphere is equal to 4/3 * pi * r^3.
if the diameter is 6, then the radius is 3.
volume = 4/3 * pi * 3^3 = 113.0973355.
the spherical weather balloon will be buoyant enough to lift the meteorological instruments and stay aloft.
