I am starting this thread as a place where we the pgites share the important aspect of QA , for the larger interest of the junta.

GEO.

Ratio of circle to the largest square within it is == pie : 2.
Ratio of circumcircle : incircle == 4 : 1.
Ratio of area : circumference of circle == r : 2.

perimetre of a semi-circle == 36 * r / 7
In a circle an equilateral triangle have max. area.

That all for today , more to follow from my side and hopefully from other side also...!

If we have to divide n distinct balls into r groups: the no. of ways posibble is very simple using the concept of "walls and balls".
The formula is :n-1
C
r-1.
If even a group of zero is also allowed then there will be a slight modification to the above formula. and is :n-r-1
C
r-1.
