Calculating either the circumference or area of a circle requires knowing the circle's radius. A circle's radius is the distance from the center of the circle to any point on the edge of the circle. Radius is the same for all points on a circle's edge. One of your problems might give...
The radius of a circle is the straight-line distance from the very center of the circle to any point on the circle. The nature of the radius makes it a powerful building block for understanding many other measurements about a circle, for example its diameter, its circumference, its area and...
