# Circle| Circle Circumference

Circle – In this article we discuss about Circle circumference, Circle area formula, circle formula, circle diameter. Circle Circumference is similar as circle perimeter.

## Circumference Of Circle

Circumference of circle means the length of the boundary of the circle. It is is similar as perimeter but in the case of circle it is called as circumference.

To find out the Circumference of the circle is multiplication of 2 with pie and the radius.

## Circle Area

Area of the circle means inside space in the circle or space in between the circle is called area of the circle.

### Circle Area Formula

Area formula of circle is the multiplication of pie with the radius square and the value of pie is the 22/7 or 3.141.
