Ellipse Shaped Concrete Slab Volume Calculator
The Ellipse Shaped Concrete Slab Calculator provides essential calculations for constructing an elliptical concrete slab. By entering the major (Length A) and minor (Length B) axis dimensions, slab depth, and waste percentage, users can determine the slab's area, perimeter, and concrete volume required in cubic feet, cubic yards, and cubic meters. This calculator assists in planning materials efficiently and managing project costs.
Ellipse Shaped Slab Calculator
Calculator
- enter the length of A in feet
- the length of B in feet
- the slab depth in inches
- waste factor (if required) in a percentage
Results
- the area of the slab in square feet
- the perimeter (circumference) of the slab in lineal feet
- amount of concrete needed in cubic feet
- concrete needed in cubic yards
- required concrete in cubic metres
Formula
Area = 𝛑MN
Perimeter = 2𝛑√(M²+N²)/2
where 𝛑 equals 3.14159
M is length A ÷ 2
N is length B ÷ 2
To convert cubic feet to cubic yards, multiply cubic feet * 0.037037037037037
To convert cubic feet to cubic metres, multiply cubic feet * 0.028316846592
To convert cubic yards to cubic metres, multiply cubic yards * 0.764554857984
Example Calculation
Length A = 22 feet Length B = 10 feet Depth = 6 inches
Area
M = 22 ÷ 2 M = 11 N = 10 ÷ 2 N = 5
3.14159 * 11 * 5 = 172.787595947 rounded to 172.79
The surface area of this slab is 172.79 square feet.
Perimeter
2 * 3.14159 * √(11² + 5²) ÷ 2
2 * 3.14159 * 8.544 = 53.683558797 rounded to 53.6
The perimeter (circumference) of the slab is 53.6 lineal feet.
Volume
Multiply the area square footage by the depth of the slab. First, convert the 6 inches to feet by dividing by 12.
6 ÷ 12 = 0.5
6 inches = 0.5 feet
172.79 * 0.5 = 86.395 rounded to 86.4
You will need 86.4 cubic feet of concrete for this slab.
