16.2 in.

Step-by-step explanation:

Vol. of cylindrical tank = Bh, where B is the area of the base

Since the base is a circle, B = $\pi r^{2}$

r = 18.5/2 = 9.25 and let's use 3.14 for π

So. 4356 = $3.14(9.25^{2} ) h$

= 268.66625h

h = 4356/268.66625

h = 16.2134... = 16.2 in to the nearest tenth of an inch

F(x)=830(1.2)^x

Each year the number of students is 1.2 times the number the year before. Or you could say that each year the enrollment increases by 20%.
