Answer:    cubic units.
 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:
