In this video, we solve a beautiful geometry problem involving two concentric circles and a chord tangent to the inner circle.
With just one clever observation, a simple right triangle appears and suddenly the area between the circles becomes obvious.

No complicated formulas, no guessing radii, just clean geometry and one satisfying conclusion.

Pause the video and try solving it yourself before watching the full explanation, then stick around to see how tangency, perpendicular radii, and the Pythagorean theorem work together perfectly.
