The weight calculation formula of street lamp pole is as follows:
The lamp pole is equivalent to a round table, and the side area of the round table is calculated according to the round table
The formula for calculating the side area of the cone is s = π (R1 + R2) L
S=π（175/2/1000+80/2/1000）×11×4/1000×7.85=0.13835t
0.13835t×1000kg/t=138.35kg
