13 inches = 13/12 feet
area =pi(diameter)2 (1/4)
= pi(13/12)2(1/4)
= pi(169/144)(1/4)
=pi(42.25/144)
=.92175 square feet
3,800 square feet at a 4-inch depth requires 46.91 cubic yards.
To calculate the volume of cement slurry needed to fill a 12-inch diameter well that is 1400 feet deep, first determine the volume of the well in cubic feet. The formula for the volume of a cylinder is V = πr²h. The radius (r) is 6 inches (0.5 feet), and the height (h) is 1400 feet, resulting in a volume of approximately 1318.69 cubic feet. Converting this volume to barrels (1 barrel = 5.615 cubic feet) gives about 235 barrels of cement slurry required to fill the well.
An 80-pound bag of concrete typically yields about 0.6 cubic feet of mixed concrete. To determine the square footage it can cover, you need to know the thickness of the slab you're pouring. For example, if you're pouring a 4-inch thick slab, an 80-pound bag would cover approximately 12 square feet.

To determine how many half-inch iron rods make up 1 ton, we first need to know the weight of a single half-inch iron rod. A half-inch diameter iron rod typically weighs around 0.668 pounds per foot. Since there are 2,000 pounds in a ton, it would take approximately 2,992 feet of half-inch iron rod to equal 1 ton. Therefore, the number of half-inch rods needed depends on their length; for example, if each rod is 10 feet long, you would need about 300 rods to make up 1 ton.
