How to calculate Linear Feet Around a Circle
Formula: Diameter x 3.1416 = Linear Feet Around a Circle
Example: Length Around an 18 foot diameter round Swimming Pool
18 ft x 3.1416 = 56.55 ft (total linear feet around pool)
To add 2 feet of stone (3 inches deep) around this pool: 56.55 feet x 2 feet= 113.10 feet
113.10 feet x 0.25 (3 inch depth) = 28.28 Cubic Feet
28.28 / 27 = 1.05 Cubic Yards
How to calculate the square footage inside a circle
Formula: Length x Width x 0.7854 = Square Feet
Example: Square footage inside a 24 foot diameter round Swimming Pool
24 feet x 24 feet = 576 feet
576 feet x 0.7854 = 452.39 Square Feet (total inside pool)
To add 4 inches of sand evenly across pool:
452.39 feet x .33 (4 inches depth) = 149.29 Cubic Feet
149.29 / 27 = 5.53 Cubic Yards
To be safe, always round up. You would order 6 Cubic Yards of sand.
How to calculate coverage for a standard driveway or pad
Formula: Diameter x 3.1416 = Linear Feet Around a Circle
Example: Length Around an 18 foot diameter round Swimming Pool
18 ft x 3.1416 = 56.55 ft (total linear feet around pool)
To add 2 feet of stone (3 inches deep) around this pool: 56.55 feet x 2 feet= 113.10 feet
113.10 feet x 0.25 (3 inch depth) = 28.28 Cubic Feet
28.28 / 27 = 1.05 Cubic Yards
How to calculate coverage for an L-shaped driveway or pad
Example: L-Shaped Driveway or Pad to be covered with stone, 7 inches deep. The calculation is done in two sections.
18 feet x 40 feet = 720 Square Feet
10 feet x 40 feet = 400 Square Feet
400 feet + 720 feet = 1,120 Square Feet
1,120 x .58 (7 inch Depth) = 649.60 Cubic Feet
649.60 / 27 = 24.06 Cubic Yards
