Students will learn about radius, diameter, circumference, and area. We give a quick introduction to the circle. So, the circumference is about 31.5 feet around. Diameter and Radius (Remote Authentication Dial in User Service) are two protocols used for AAA (Authentication, Authorization, and Accounting) services. % Progress . First we define the important parts of a circle: the radius, diameter and circumference. ø = Circle diameter; r = Circle radius; Radius of Circle. Just divide by two; half the diameter is the radius. The diameter will always pass through the center of the circle. This is the diameter of a circle that corresponds to the specified radius. The formula used to calculate circle radius is: r = ø / 2. They will also learn about a compass and how to use one. What is the relationship? Circle. If the radius is 22.5 centimeters, the diameter would be 45 centimeters.
