Formula for calculating volume of truncated hollow cone? A hollow truncated cone is a geometric shape that is cone-shaped. The formula to calculate the volume is s^2=h^2 + (R-r)^2.
R1 = Radius of the base. R2 = Radius of the top. h = height of the truncated cone. by my algebra, same as: V=1/2*pi*(R12+R22)*h. The alternative algebra is not correct. Using the same positive values for R1 and R2 and the answers are not equivalent. The formula at the top matches Wikpedia and other sources on the web.
