2 radii = one diameter
Well, the equation for finding the circumfrence of a circle is (diameter)(pi). That is diameter times pi. since the diameter of a circle is 2 radii, we can say that there is 2(pi) radii in a circle.
They are congruent circles
It is the smaller of the 2 part divided between 2 radii
the single form of radii is radius
