Find the radius of the smallest circular disk large enough to cover every isosceles triangle of a given perimeter L.

Find in-radius for the given triangle

A circular disk of unit radius is filled with a number of smaller circular disks arranged in the form of hexagon. Let A_n denotes a stack of disks arranged in the shape of a hexagon having 'n' disks on a side. The figure shows the configuration A_3. If A be the area of large disk, S_n be the number of disks in A_n configuration and r_n be the radius of each disk in A_n configuration, then lim_(n->oo)(S_n)/n^2 lim_(n->oo) nr_n
