How many yards of sand to cover 20 foot circle 2 inches thick?

Answer 1

To find the amount of sand needed, first convert the thickness from inches to feet: 2 inches is 1/6 of a foot. The area of a 20-foot circle is calculated using the formula (A = \pi r^2), where the radius (r) is 10 feet. This gives an area of approximately 314.16 square feet. To find the volume of sand required, multiply the area by the thickness: (314.16 \times \frac{1}{6} \approx 52.36) cubic feet. Finally, convert cubic feet to cubic yards (1 cubic yard = 27 cubic feet), resulting in about 1.94 cubic yards of sand needed.
