Your working at a concrete company that specializes in commercial-grade columns. a cylindrical column with a diameter of 3 feet and height of 10 feet is to be made of concrete. how many cubic yards of concrete are needed to fabricate the column?

The volume of a cylinder, which this is, is V = πr^2h, where r is the cylinder raidus and h is the cylinder height.

Here the volume is   V = π(3/2)^2*10 ft^3, or π(9/4)(10) ft^3, or (90/4)π ft^3.

1 cubic yard is equivalent to 27 cubic feet.  Thus, multiply (90/4)π ft^3 by the appropriate conversion factor:

(90/4)π ft^3         1 yd^3

* = 0.833 yd^3

          1               27 ft^3

0.833 cubic yards of concrete would be needed to fill this column form.

answer: i guess 5 units?
