Why Pi Equals 3.14159
This animation reveals where pi comes from by tracing a circle's circumference against its diameter, showing the ratio is always about 3.14. It builds the formula pi = circumference divided by diameter, then reveals the constant's endless decimal digits scrolling across the screen. Multiple circles of different sizes confirm the ratio never changes, ending with the circle morphing into the pi symbol. Useful for algebra students learning where pi originates and why it stays constant.

The prompt that made it
Create a vertical 9:16 educational animation for a YouTube Short about the mathematical constant π (pi). Scene 1: Show a beautiful animated circle appearing on a clean dark background. Slowly draw the circle's circumference and then show a straight line across the center labeled "diameter". Scene 2: Animate the circumference being measured and then compared with the diameter. Visually demonstrate that the circumference is always about 3.14 times the diameter. Scene 3: Display the mathematical formula clearly: π = circumference ÷ diameter Scene 4: Show the number π appearing dramatically: 3.141592653589793... The digits should appear one by one and continue moving smoothly across the screen. Scene 5: Show several different-sized circles. Demonstrate that although their sizes are different, the ratio of circumference to diameter remains the same: π. Scene 6: End with a visually impressive mathematical animation where the circle transforms into the symbol "π". Style: modern educational animation, clean mathematical graphics, smooth motion, visually interesting, suitable for teenagers and students, high quality, no unnecessary characters, no clutter. Use clear mathematical symbols and make all numbers and formulas easy to read. Duration: 30–45 seconds. Format: 9:16 vertical. Audience: Algebra students
