Understand properties of circles (radius, diameter, circumference)

In this lesson, we will explore the different parts of a circle and how to calculate its circumference.

Radius

• The radius is the distance from the center of the circle to any point on the edge.

Diameter

• The diameter is twice the radius. It goes from one point on the edge, through the center, to another point on the edge.

Circumference

• The circumference is the distance around the circle.
• You can calculate it using the formula: C = 2πr or C = πd.

Now, let's practice identifying and working with parts of a circle!
