Dia of Core of circle = d/4.
Dia of Circle = d.

Area of Core/Area of Circle = 1/16 will get.

assuming non eccentric ccondition
e=D/8(Radius of core)
area of column=(22/7)xD^2/4................Eq 1
area of core=(22/7)X r^2
area of core= 22/7x D^2/64.....................Eq2
now dividing eq1/eq 2
we get 16

Area or colum = pi x D2/4
Radius of core, r = D/8
Area of core = pi x r2 = pi x (D2)/64
Ratio , pi x D2/4 / pi x (D2)/64 = 64/4 =16
