Area - Area Of A Circle
By mrmaisonet
Once you know what 'radius' and 'area' mean, watch this video to learn how to calculate the area of a circle. Pay attention to the common mistakes, such as using an incorrect order of operations.
Definition of a Circle - Radius of a Circle
By yourteachermathhelp
Students learn the definitions of a circle (is a set of points in a plane that are a given distance from a given point in the plane), the given point is called the center, and the distance from the center to the circle is called the radius. Whichever point on the circle is chosen the distance to the center of the circle will be the same, so all radii of a given circle are congruent. Good quality video for grade four and up.

Circles: radius, diameter, circumference and Pi | Geometry | Khan Academy
By Khan Academy
The radius is the distance between the center and any point on the circumference of a circle. The diameter is always twice the radius. The circumference is the perimeter of the circle.
Area of a circle
By Khan Academy
Learn how the number Pi allows us to relate the radius, diameter, and circumference of a circle.
Area of a circle
By Khan Academy
In this example, we solve for the area of a circle when given the diameter. If you recall, the diameter is the length of a line that runs across the circle and through the center.
