The circle is a highly symmetric shape: every line through the centre forms a line of reflection symmetry, and it has rotational symmetry around the centre for every angle. Its symmetry group is the orthogonal group O (2, R ). The group of rotations alone is the circle group T. All circles are similar.
Circle Formulas. Area of a circle: The area of a circle is the region enclosed inside the circle. The area of a circle depends on the length of its radius. Area = π r 2.
