Answer: 5086.8π inches cubed

Explanation:

First, the formula is V=πr²h (v = volume, r = radius, and h = height)

Then, lets convert the diameter to radius by dividing by 2.

18 / 2 = 9

Now lets plug in our numbers!

V = 3.14 · 9² · 20

V = 3.14 · 81 · 20

V = 3.14 · 1620

V = 5086.8

Hope this helps you :)
