Another problem...

If equilateral triangle ABC is inscribed in a circle and arc ABC = 24. what is the approximate diameter of the circle?
Answer: 11.

But I could not work it out? Can anyone help me here?

The three points of the triangle will devide the circumfrance of the circle in 3 parts.. And you are given sum of two parts..

Rest you can figure out :-)

thanks for finding that.

on problems with lots of keywords in the prompt, such as this one, you should try to search the forum for the problem before you post a new thread -- we really don't want lots and lots of threads for the same problem.
thanks.
