Calculation rules please according to the quota, the specific calculation volume is divided into pile body (cylinder volume calculation) + expanding head (circular table body volume) + straight section (cylinder volume) + the bottom of the nest (ball missing body volume), the formula is as follows:

Cylindrical volume V = cylindrical cross-sectional area * cylindrical height

Circular table volume V = πh/3*(upper circle radius squared + lower circle radius squared + upper radius * lower radius)

ball missing body volume V = πh/6*(3*a*a-h) a ball missing body volume V = πh/6*(3*a*a-h) a ball missing body volume. lower circle radius)

Sphere missing body volume V = πh/6*(3*a*a-h) a ---- sphere missing body circle cross-sectional area radius
