To calculate the amount of sand needed for a 14-foot diameter circle that is 3 inches deep, first convert the diameter to radius: 14 feet ÷ 2 = 7 feet. The area of the circle is π (approximately 3.14) times the radius squared: π × (7 feet)² ≈ 153.94 square feet. Then, multiply the area by the depth in feet (3 inches = 0.25 feet): 153.94 sq ft × 0.25 ft = approximately 38.49 cubic feet of sand needed.
22/7x6x6x6 cubic inches
Half a cubic foot.
An area 10 foot x 10 foot is 100 square feet. 100 cubic feet of sand would cover it with a one foot deep layer of sand. If the sand needs to be 6 inches deep, then 50 cubic feet are be needed, or 25 cubic feet if the sand is to be 3 inches thick.
It depends on how deep it is. If it is 6 inches deep, you will need 77 yards.
To calculate the amount of gravel needed, first find the area of the circle using the formula A = πr². The radius of an 18-foot circle is 9 feet, so the area is approximately 254.47 square feet. To find the volume needed for a depth of 4 inches (which is 1/3 of a foot), multiply the area by the depth: 254.47 sq ft × 1/3 ft = about 84.82 cubic feet of gravel.
