sorry. A circle of radius 12 has a total circumference of 75.4
so there is no way the arc length could be 77 cm

good observation.
I answered this same question yesterday.
Since he wanted the base radius of the cone, all we need is the
77 cm of the arc.
I totally ignored the radius of the original circle since it did not enter
the problem. Should have checked to see if valid.
Of course with the "search" feature not working for the last 3 years on
this webpage, I now cannot find that question to see if he responded.
