Solve the problem.A balloon in the shape of a sphere is deflating. Given that t represents the time, in minutes, since it began losing air, the radius of the balloon (in cm) is 
Let the equation V(r) = 
?r3 represent the volume of a sphere of radius r. Find and interpret (V ? r)(t).
A. (V ? r)(t) = 
?(t - 23)3; This is the volume of the balloon (in cm3) as a function of time (in minutes).
B. (V ? r)(t) = 
?(23 - t)3; This is the volume of the balloon (in cm3) as a function of time (in minutes).
C. (V ? r)(t) = 23 - 
?(23 - t)3; This is the volume of the air lost by the balloon (in cm3) as a function of time (in minutes).
D. (V ? r)(t) = 
?(23 - t)3; This is the volume of the air lost by the balloon (in cm3) as a function of time (in minutes).
