A: The diameter of a circle is the length of a straight line going from one side of a circle to the opposite side. To measure the diameter, simply choose two points on the edge of a circle that are directly across from each other, and measure the distance between these points.
Radius, Diameter and Circumference. The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle. And here is the really cool thing: When we divide the circumference by the diameter we get 3.141592654... which is the number Ï (Pi) So when the diameter is 1, the circumference is 3.141592654...
