Circles Radius Diameter & Pi Math Learning Upgrade



~Lyrics~

A circle is a shape with all points on the circle the same distance from the center point.
A radius is a straight line from the center to the circle's edge.
A diameter is a line that cross the end point of a circle that passes through the center point.
A circumference is the distance around a circle


:::Chorus:::

diameter d is twice the radius
radius r is half the diameter
pi is circumference, c divided by the diameter
pi is 3.14 - approximately
circumference is pi d or 2 pi r
area is pi r square

  3. I'm amazed, I must say. Rarely do I come across a blog that's equally educative
    and interesting, and without a doubt, you have hit the nail on the head.
    The problem is something which too few folks are speaking intelligently about.
    I'm very happy that I stumbled across this during my hunt for something concerning this.

    much as this one. I mean, Yes, it was my choice to read through, nonetheless I genuinely thought you
    would have something useful to say. All I hear is a bunch of crying about something you could possibly fix if you
    were not too busy looking for attention.
