[-/1 Points] DETAILS SCALCET9 1.3.060.MI. MY NOTES ASK A spherical balloon is being inflated and the radius of the balloon is increasing at a rate of 2 cm/s. (a) Express the radius r (in cm) of the balloon as a function of the time t (in seconds). r(t ) = cm (b) If V is the volume of the balloon as a function of the radius, find V . r. ( V . r ) (t ) = Interpret your answer in the context of the problem. This formula gives the amount of time (in seconds) the balloon has been inflating as a function of V. This formula gives the volume of the balloon (in cms) as a function of time (in seconds)
