• The circle is the shape with the largest area for a given length of perimeter (see Isoperimetric inequality). • 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.
WebDiameter of the circle = 32 cm. So, radius of the circle = diameter / 2 = 32 / 2 = 16 cm. Area of quadrant ² = π r 24 = 3.14 × 16 × 16 4 = 200.96 cm².
