Looks like there are two pi radii around the circumference of a circle
I understan the radian is a unit of measurement. its a straight line from the outer edge of circle to the centre of a circle.
so the how many time can trace a radian around a circufrence of a circle is about six times with a little left over. As radia is the lengh of the raduis. raduis is half a circle
my qustion is when reffering when its 2 pi to circufrence of a circle does that mean . lengh of measurement is 2 raduis(radii) to a circle.
this i got from a site on mats below and that what confusing me...
Ive attached an image .. see image is that correct
(Looks like there are two pi radii around the circumference of a circle, or about 2 )
