Circular cone volume = (<font face="Comic Sans MS">π</font><font face=Arial> • r2 •</FONT> h) / 3
Side area = (<font face="Comic Sans MS">π</font> • r • slant height)
Circular truncated cone

Do you know the circular cone? The upper tip is eliminated by the circular truncated cone. He should be a cylinder. The top view is two round sleeves, the main view is trapezoidal.
Set the bottom radius to r, the bottom radius to R, and the height to h
Then V = (1/3) * π * h * (R ^ 2 + Rr + r ^ 2)
Conical table volume = (π • high height • (Ra^2 + Ra • Rb + Rb^2) / 3)
Side area = (π • (Ra + Rb) • Oblique height)
