Answer: 5086.8π inches cubed
Step-by-step 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 :)
