Similar to circle sphere is a two dimensional space where the set of points that are at the same distance r from a given point in a three dimensional space. In analytical geometry with a center and radius is the locus of all points is called sphere.
The distance around a circle is called its circumference.The circumference of the circle is
The object is to find the circumference for the given circle as follows. The radius of the circle is r=21
Then the circumference of the circle is,
So the circumference of the circle is approximately 132 cm.
