Answer:

hello your question is incomplete attached below is the complete question

answer : -2400 π

Step-by-step explanation:

dr/dt = -12 km/s

h = 2.5 km

r = 40 km at some instant

hence the rate of change of Volume of cylinder at that instance

= dv / dt = [tex]d(\pi r^h ) / dt[/tex]  

              = [tex]\pi h\frac{d(r^2)}{dt}[/tex]  = [tex]-\pi h *2r *dr/dt[/tex]

hence ; dv / dt = -2400 π
