Answer / rajnath rajbhar

Density of reinforcement steel is = 0.00785 kg/mm2 for 1 mm length
Apply formula M=D x V

M = (0.00785 x 3.142 x d x d)/4
M = 0.006166175
for remembering we are using 1/162.2 as it is equal to 0.006166175

So for unit weight we use = (d x d)/ 162.2

Answer / bilal ali khan

Kamaal karte Hoon Main Batata Ho Aur Exact Nikal Ke Dikhata Hoon
Weight=area x thickness x density=LENGTH X AREA X DENSITY
densiy of steel=7850kG per m^3
area=(22 x d^2)/(7 X 4)=(PIE X D KA SQUARE)/ 4
LIS LENGTH
NOW WEIGT=(7850 X L X 3.14 X D^2) / 4
WEIGHT=(L X D^2 ) / (4/(3.14 X 7850))
WEIGHT= (L X D^2) / 0.0001618
NOW U KNOW IN CONVERT L INTO M AND D IN MM U WILL GET UR RESULT dia*dia/162.2
So i know its origin exactly

Answer / vj

weight=density*volume
weight=density*area*length
here,density=7850kg/m^3=7850kg/1000000000mm^3=.00000785
now,
weight=.00000785*3.14*d^2*length/4
weight=.00000616225*d^2*length(m)
weight=.00616225*d*d
