A Student Asked This Question in Class!

A student asked a very interesting question during our classroom session on Areas Related to Circles:

👉 Why do we use r² (radius squared) when calculating area?

👉 Why do we use 2πr when finding the circumference or arc length?

Instead of simply giving a formula, I explained it with a practical visual demonstration on the board so that everyone could understand the logic behind these concepts.

In this video, you’ll learn:

✅ Why area formulas contain r²

✅ The meaning of 2πr

✅ The difference between area and length measurements

✅ Area of a sector explained visually

✅ Arc length made easy

✅ Conceptual understanding instead of rote memorization
