Have you ever wondered why a 16-inch pizza 🍕 is actually FOUR times bigger than an 8-inch pizza, not just double? 🤔
In this geometry lesson, we break down the relationship between Scale Factor (k) and Area Ratio (k²). We'll explore how changing the length of a shape affects its area and surface area in ways that might surprise you! 📐
Perfect for geometry students and math enthusiasts looking for a visual explanation of square laws.
Topics covered:
🔹 Definition of Scale Factor (k)
🔹 Visualizing Area Growth
🔹 The k² Formula
🔹 3D Surface Area examples
🔹 Real-world application
