WebWe have derived the area of the circle. Method 2 This time, consider dividing the circle into thin circular strips (as shown in the top half of the figure below), cutting open each strip, and stacking them one over another (as shown in the bottom half). That gives us something of a triangular shape. WebTo derive it, we use the formula for the circumference (perimeter) of a circle. We show that the area of a circle is equal to the area of a rectangle whose one side is equal to the …
