Radius, Diameter and Circumference
A circle is easy to make: Draw a curve that is "radius" away
from a central point. And so: All points are the same distance from the center.
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 π (Pi)
*Don't Forget:
The length of the words may help you remember: Radius is the shortest word Diameter is longer (and is 2 × Radius) Circumference is the longest (and is π × Diameter)
