CIRCUMFERENCE OF A CIRCLE...

Circumference (C) is the distance around the outer ring.
C = Pi x d or Pi2r/2Pir
Pi is a constant and is approximately equal to 3.14.

Example















Radius (r) is the distance from the center to the outer ring...
Picture















The diameter (d) of circle is twice the length of the radius...
D = 2 x r or 2r

AREA OF A CIRCLE...
Area = Pi x r²
Pi = 3.14
Radius is the distance/length from the center to the outer ring...
