AI Drawing Prompt Reference
Draw a sphere with adjustable radius using a slider. Display the volume formula V=4/3πr³ and surface area formula TSA=4πr² next to the sphere, showing corresponding numerical values. Include a text field for users to input guesses and provide immediate feedback with scores. Label the radius, volume, surface area, guesses, and scores using text. Add a check answers button for automated grading.
