Answer choice 4.  577 pounds

Step-by-step explanation:

Given a cylindrical steel post with dimensions:

Volume of a cylinder is given as:

Volume =

Substituting all the given values we have:

cubic feet

Since, 1 cubic foot of steel weights 490, 1.1775 cubic foot of steel would weigh  

Rounding to nearest pound, we would get pounds as the answer.

Answer choice 4 is correct.

-4

step-by-step explanation:
