I am leveling an above ground, round pool that is 15' in diameter. I need to know how much sand (tons) I need to layer the ground with 2" of sand.

You need about 29.4 cubic feet. That is a little over 1 yard. 1 yard =27 cubic feet.

here is the calc

area of circle is Pi x r x r= 3.14x7.5x7.5 = 179.6 sq feet

volume = area x depth = 176.6 x 2/12= 29.4

ACD - hi, you're talking a lot of sand! Using Joed's math formula above, the radius of your circle is 27.5 feet. Radius x radius (or radius squared) is 27.5 x 27.5 = 756.25 feet. Take that times "pi" (the 3.14 number above), and you have 756.25 x 3.14 = 2374.625 square feet. Since you want it 1 foot deep, you now have 2374.625 cubic feet, or 87.95 cubic yards. I hope this helps you - regards! Jim D/Heathsville, VA
