Final answer:
No, it's not possible for a cone and a cylinder to have the same height and radius while having different volumes.
Step-by-step explanation:
To determine if it is possible for a cone and a cylinder to have the same height and radius while having different volumes, we need to compare their volume formulas. The formula for the volume of a cone is V = 1/3 * π * r² * h, and the formula for the volume of a cylinder is V = π * r² * h. Since the volumes are different, it is not possible for the cone and the cylinder to have the same height and radius.
