Triangle in circle

Vertices of the triangle ABC lies on a circle with radius 3 so that it is divided into three parts in the ratio 4:4:4.

Calculate the circumference of the triangle ABC.

Correct result:

o =  15.6


Φ1=36044+4+4=120 Φ2=36044+4+4=120 Φ3=36044+4+4=120  a=23sinΦ12=5.2 b=23sinΦ22=5.2 c=23sinΦ32=5.2  o=a+b+c=15.6
