Example 2: Let’s find the area of the circle. This is what I have so far, but it produces a very strange resulting image, but it is rotated somewhat: Assuming you're using the cv2 version, that code finds the center of the image you want to rotate, calculates the transformation matrix and applies to the image. Tau is defined as the ratio of the circumference to the radius of a circle.
Unlike other floating point rounding errors, these seem to warrant exception because we're talking about whole integer expectations.
