Welcome to this video on the radius, diameter, and circumference of a circle. Radius of a Circle Radius is the length from the midpoint of the circle to the outer edge of the circle.

Diameter of a Circle Diameter is the full length of the circle running from the edge, through the midpoint, all the way to the other side.

Circumference of a Circle Now, circumference is the distance around the outside edge of this circle. Calculations If someone were to just kinda hand you a piece of paper with a circle on it….
