SR=l/r.
r=√ (i/A).

i= π D^4/64.
A=π D^4/4.
So r=D/4.
SR= 4.4/.32/4.
SR= 55.ans.

For solid column slenderness ratio is effective length /least lateral dimension right?

kl/r = slenderness ratio.
k assumed = 1.
r for circular column = 0.25 Diameter.
440/(.25*32) = 55.

Slenderness ratio = L/r.

r = 0.25 D.
= 0.25x32 = 8.

Slenderness ratio = 440/8 = 55.

K=d/4.
=0.32/4.
=0.08.

S.R=l/k.
=4.40/0.08.
=55.

S.R=55.

Slenderness ratio = 4l/d.
= 4 x 4.40/32cm convert it to m.
= 4 * 4.40/0.32,
= 55.

Sr = length/least radius of gyration.

The Radius of gyration = root (Moment of inertia of circular columns/Area of the section).

What is the formula?
