Can you explain why you took this step?
Of course! In a cone, the radius is the distance from the center of the base to any point on the base. The base of the cone is a circle, and the diameter is the distance across the circle passing through the center. Since the base of the cone has a diameter of 8, the radius (which is half the diameter) is 8/2 = 4.
I hope this explanation helps clarify why the radius in this case is 4. Let me know if you have any other questions!
