00:00If you keep peeling away the circumference of a circle into lines and stack them until the circle
00:07disappears, the layers will eventually create a triangle with a base as wide as the original
00:14circumference and a height as tall as the radius. Now this is because the area of a triangle is half
00:22of the base multiplied by the height. So that becomes one half times the circumference times
00:29the radius, showing that the area of the circle matches the area of the triangle.
