This is called as the perimeter of the circle.

The units of the perimeter are mm, cm, m, km

Formula for the circle:2 [Pi] r

Where ; r is the radius of the circle

Circumfrence of a circle: [Pi] * d

where ;c is the circumfrence

d is the diameter,in the next blog we will learn about what is trigonometry and factor trinomial calculator,hope you like the above example of perimeter of a circle,please leave your comments if you have any doubts.
