If the temperature remains constant, the pressure of an enclosed gas is in- versely proportional to the volume. The pressure of a certain gas within a spherical balloon of radius 9 inches is 20 lb/in?. If the radius of the balloon in- creases to 12 inches, approximate the new pressure of the gas. Sketch a graph of the relationship between the pressure and the volume.
