@logitech or anyone else that can help, is the formula/ratio you provided only applicable to ab equilateral triangle inscribed within a circle, or any triangle inscribed within a circle? Assuming the former but please advise.

Thank you!

logitech wrote:Guys I have seen this same problem so many times over and over again..I carried the whole calculation and found out:

Area of Triangle / Area of Circle = 3xSQRT(3)/4Pi

In our example:

3xSQRT(3)/4Pi = 9SQRT(3)/Area of Circle

Area of Circle : 12 pi

In your face GMAT!!

:lol:

Put it in a flash card ( if you have time and patience, you can drive the formula )
