CIRCLESCircumference-Radius-Diameter BY: Vanessa Saldana
TEKS: Math 6th Grade (6) Geometry and spatial reasoning. The student uses geometric vocabulary to describe angles, polygons, and circles. The student is expected to: (C) describe the relationship between radius, diameter, and circumference of a circle
Lets learn a new song about ………. CIRCLES
Call me Ra(y)-Dius You know my friends and me, We move in proper circles of plane geometry………… R = C/2 PI R = D/2
And our good friend Sir CumferenceHe's always with us, too C = PI X D C = 2PI X R
Our relationships are constant. You can't change them if you try. Circumference divided by diameter is Pi C / D = PI
? Or Should I say ………… 3.14159 Or so the truth is that no body seems to know
