Phyxon on Instagram: "🧠 “Ever wondered why the area of a circle is πr² — not just because they said so?” 🤔 Here’s how the formula for the area of a circle isn’t magic — it’s pure geometry & calculus 🌀 We take a circle and divide it into infinitely thin slices (sectors) — like cutting a pizza 🍕 When rearranged, those slices form a shape close to a rectangle, where: The height = radius (r) The base = half the circumference = πr So, Area = base × height = (πr) × r = πr² That’s how the area of a
