00:41Diameter
00:42A diameter is a line segment that passes through the center connecting two points on the circle.

00:50A radius is a line segment connecting a point on the circle to the center.
00:58Diameter and Radius
01:00Notice that if you connect two radii, you will get a diameter, which means that the diameter is twice the radius.
01:07Circumference
01:08The distance around the circle is called the circumference.
