Hey there!
The formula for the volume of a cylinder is
, which is essentially the base multiplied by the height.
If our diameter is six, then our radius is three, so we can solve for our base below. We will use 3.14 for pi.

Now, we multiply this by our height of four.

Therefore, our volume is 113.04 cubic units.
I hope this helps!
