Answer: If a circle was flattened by pushing down on it, it would most likely form into the shape of an ellipse which has two focal points.
Explanation:
An ellipse is defined as the enclosed curve with two focal points.Sum of the Distance of any point on the curve from the two focal point remains constant.For example: An orbit of the earth is elliptical shape.
So, when we flattened circle we will obtain an ellipse with 2 focal points.
