For a hole 36" deep X 18" diameter, you would need approx. 1/5 cu. yd. concrete.
r=1/2 d r=6 A=3.1415 x (6x6) A is approx. 113.1

Area of a Circle = (pi)(r^2) Diameter = 2r If the diameter of the circle is 12, then the radius has to be 6. If the area of a circle is pi times the square of the radius, and the square of 6 is 36 (6x6), then the area of the circle is 36pi.

I use one bag to 1 1/2 bags per hole and fill the rest of the way back with tamped topsoil... whatever came out of the hole.
