Lyrics:

Within a circle
there is a radius
and a diameter
that's twice the radius
and cirumference
is in a ratio with the diameter
and it's call "Pi"
and it is
3.141592
65358979
32384626
43383279

3.141592
65358979
32384626
43383279

Pi goes on forever and ever and ever.
Pi is an irrational number and it is

3.141592
65358979
32384626
43383279
and it never stops.
