Answer:
The radius is decreatsing at a rate 0.78 cm per second.
Step-by-step explanation:
We are given the following in the question:

Instant radius,r = 2 cm
Instant length,l = 9cm
The radius of the cylinder decreases.
Volume of cylinder =

Rate of change of volume:

Puttiung values, we get

Thus, the radius is decreatsing at a rate 0.78 cm per second.
