Answer:
cubic units.
Step-by-step explanation:
You can use this formula for calculate the volume of a cone:

Where "r" is the radius and "h" is the height.
You know that the diameter of the base of the cone measures 8 units, then, the radius can be found by dividing the diameter by 2:

Since you already know that height and the radius, you can substitute them into the formula. Then, the volume of this cone is:


I think it’s A
