WebExample 2: Calculate the length of the arc that subtends an angle of 40 degrees at the center of a circle with a radius of 6 cm. Solution: We know the arc length formula is y 360 2 π r. In this example, y = 40 and r = 6. Substituting these values in the example, we get. Arc length = 40 360 2 3.14 6 = 4.186 cm.

• 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.
