In this equilateral triangle, the value ABC is given. The circumference should be divided by 2/3. and then proceed to find the dia. Is it correct ?

What you said is correct, except in that strictly speaking the correct way to proceed is not to divide the circumference by 2/3, but rather to divide the arc by 2/3 to find the circumference.
