nice geometry problem!!

let ABC be a triangle with AB=AC=6. If the circumradius of the triangle equals 6, then BC equals:

(a)25/3 (b)9 (c)48/5 (d)10

this is a sample question on the kvpy website.

This is quite easy.....
Sorry, i used props of triangles....
6Sinc=12, C=30 deg....

now it's cat-walk finding BC....Droping a perp from A is only 1 simple approach....
