Webb17 maj 2016 · A circle is the shape which has the most area for the smallest perimeter. Similarly for a sphere. So, changing the shape and keeping the perimeter should decrease the area. – N. Owad May 17, 2016 at 21:16 Circle is an ellipse with 0 eccentricity. When a=b, the ellipse is a circle, and the perimeter is 2πa (62.832... in our example). When b=0 (the shape is really two lines back and forth) the perimeter is 4a (40 in our example). They all get the perimeter of the circle correct, but only Approx 2 and 3 and Series 2 get close to the value of 40 for the extreme case of b=0.

WebbIn geometry, the circumference (from Latin circumferens, meaning "carrying around") is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure.
