You can use Desmos to graph these and make your own judgment as to the intercepts and rates of increase/decrease.
The ones with a base < 1 will decrease rapidly, then slowly. The one with a base > 1 will increase slowly, then rapidly. The y-intercept is the multiplier in front of the base.

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 =
Since the volume of the cylinder does not changes, we can write:
Rate of change of volume:
Puttiung values, we get
Thus, the radius is decreatsing at a rate 0.78 cm per second.
Answer:
The lateral area of a cone equals
PI * radius * slant height
=PI * 3 * 5
lateral area = 47.1238898038 square centimeters
