It depends on the spiral - there are lots of different ones, with different formulae.

To calculate the spiral ring in a pile, you first need to determine the diameter of the pile and the pitch of the spiral. The spiral ring is essentially a helical shape that wraps around the pile in a specific pattern. You can use trigonometry and geometry principles to calculate the length and spacing of each coil in the spiral ring. This calculation is crucial for ensuring the stability and load-bearing capacity of the pile structure.
Their is formula given in a code i think SP-32 L=N*Pie(D+d)+8d L=Length of Spiral rings N=Number of Spirals Pie=3.142(constant) D= Diameter of pile cage(spiral C/C) d=diameter of bar
The hypotenuse of the nth triangle has a length of sqrt(n+1)
To calculate the length of helical ring of pile, use the standard formula. The formula is pi D X the number of coils. "D" is the diameter of the coils.
The volume of a triangle can be calculated with the formula: volume=1/2*length*width*height.
