Circumference. It is the distance around a circle. Keywords: fencing, framing, edge, border.
C = π d C = 2 π r
π (Pi) Could be 3.1416, or 3.14, or 22/7, or 3 if it is an approximation.
Approximately 3 diameters equal to the circumference of the circle.
r Radius is half of the diameter
d Diameter equals to two radius (radii)
Area of Circles
