@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!
Thank you!

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