Answer:
Option D. 
Step-by-step explanation:
we know that
The volume of the cylinder is equal to

In this problem we have


substitute
-----> exact value of the volume
36100/36789=0.9812715757427492
Let

. Then

, and so as

, you have

. The limit is then equivalent to
For the first one its a slope of -2/3
The second one is 4/5
and the third one is -1/7
