1 A circle is all of the points that are a fixed distance, known as the radius, from a given point, known as the center of the circle. 2  Explore the standard equation of a circle using the applet below (Go here for a larger version).
The idea is to obtain an average. measurement, and that measurement becomes the radius. of the circle. The diameter (d) of the circle is found by. multiplying its radius by 2. The area then is computed using. the formula for a circle.
