AI Drawing Prompt Reference

Draw a sphere to demonstrate the calculation of its volume and surface area. Start by sketching a circle, then mark a point on the circle and draw arcs and rotated shapes to create a three-dimensional representation of the sphere. Connect the center of the circle to the marked point and find the midpoint. Display the volume and surface area formulas along with their calculations. The final image should include the sphere, auxiliary lines, formulas, and calculation results, suitable for high school mathematics education.
