Answer:
b
Step-by-step explanation:
Given that opulation of 100,000 decreases by 2% each year.
Now question says to write a function in terms of t that represents the situation.
Question is talking about population decrease so we can apply decay formula. which is given by:

Where A is the population at any time t.
is the initial population so 
r is the rate of decrease so r=2%=0.02
t is the number of years
Now plug those values, we get:


Hence required function is
.
The formula for volume of a cone = PI x r^2 x h/3
PI = 3.14
r = 8.5/2 = 4.25
h = 4.5
Volume = 3.14 x 4.25^2 x 4.5/3
Volume = 3.14 x 18.0625 x 1.5
Volume = 85.074375
Rounded to the nearest hundredth = 85.07 cubic cm.
