No, the distance around a circle is called the circumference. The radius is the distance from the exact center of the circle to the edge of the circle and is one half of the diameter. The diameter is one straight line passing through the center of the circle from one end to the other. The circumference can be determined from the following equation: C = pi * d or C = 2*pi*r
The centre of a circle is simply called the cnetre. The edge may called the perimeter, the circumference or the edge.
