How much would it cost to fill a circle, with a diameter of 20 feet, with Cement if the depth into the ground was a foot?
How about we call it 12 yards and our price here is 100 a yard plus tax.... so all you need now is someone to pour and finish it:) Have fun, 12 is deep, so watch the little kids.......they just love to skate thru.
I presume you want concrete, and not cement... I use a cheat method of figuring this, others may object. But a round object can be figured very close to accurate by figuring it like it's a square, and then subtract 1/5 from the result. For example, your 20' circle, figure 20' x 20' = 400 - 80 = 320' of concrete approx. There's 27 feet in a yard, so 320 divided by 27 = 11.85 yards. We'll round this up to 12 yards, and estimate the concrete delivered at $110 a yard, for an estimated total concrete cost of 12 x $110 = $1320. That's my guess.
