Here, You just need to find, Volume of a Cylinder + Volume of a cone.
So, Volume of a Cylinder = πr²h
v = π * (6)² * 16
v = π * 36 * 16
v = 576π
Now, Volume of a Cone = πr² h/3
v = π * (6)² * 3/3
v = π * 36 * 1
v = 36π
Total Volume of the figure = 576π + 36π = 612π m³
In terms of whole numbers, 612 * 3.14 = 1922 m³
In short, Your Answers would be: 612π & 1922 m³
Hope this helps!
