This is the equation for circumference of a circle. That is a massive table. C 2 p 275 m C 2 p 275 m.
This tells us that the circumference of the circle is three and a bit times as long as the diameter.
C p d o r C 2 p r. What is the formula when solved for r. The following equation describes the relation between the circumference and the radius R of a circle. Where p is a constant approximately equal to 314159265.
