Center (0,0); r= square root of 12

Standard form of circle's equation is
(x-h)^2-(y-k)^2=r^2
where (h,k) are coordinates of the centre
and r is radius
(x-0)²+(y-k)²=√12²
x²+y²=12

Ifound this on google “a skewed (non-symmetric) distribution is a distribution in which there is no such mirror-imaging. a "skewed right" distribution is one in which the tail is on the right side. a "skewed left" distribution is one in which the tail is on the left side. the above histogram is for a distribution that is skewed right.” i hope this you for what your looking for
