The circumference and area of a circle, with radius r is: circumference = 2*pi*r and area = pi*r2 Use the first to calculate r and then the second to calculate the area.

Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius

Radius x 2 x 3.14 = Area * * * * * That is the formula for the circumference! The area = pi*radius2

The circumference of a circle is the distance arround the edge of the circle. The area of a circle is how big the inside of the circle is.

The area of a circle, if its circumference is 20π, is: 314.16 square units.
