AI Drawing Prompt Reference

Create a 3D solid geometry figure comparing the volumes of a cylinder and a cone. Start by drawing a circle on the coordinate plane as the base, then extrude it vertically to form a cylinder. Next, translate the same circle horizontally by a certain distance, and use this translated circle as the base to construct a cone with the same height as the cylinder. Both solids share the same base radius and height. Connect the center of the cylinder's base to a point on its circumference with a line segment, and display the volume values for both the cylinder and the cone. The layout should clearly show the spatial relationship between the two solids for easy volume comparison.
