Ross will make a water balloon that can be modeled with a sphere. A constraint he must consider is that when the radius of the b
alloon exceeds 5 inches, the balloon will pop. If he uses a garden hose with a flow rate of 12 gallons per minute to fill up the balloon, for how many seconds can he fill it before it pops? Round to the nearest tenth of a second. (1 gallon = 231 cubic inches) Enter your answer in the box.
