given the linear ratio between the diameters, a : b the fundamental frustum constant, m, is given by:

name the variables such that a > b

c = a^3; d = b^3

m = (c - d) /3

pi/4 *m /c = vol of frustum relative to rectangular prism containing the full cone (multiply this by 4 *R *H)

pi/4 *m /d = vol of frustum relative to rectangular prism containing small cone (multiply this by 4 *r *h)

believe it or not, this is less work than the way you did it, and it generalizes to all frusta. just replace the fundamental circle constant, pi/4, with the shape constant for whatever the base is.

Thank you so much! You explained it so quickly and easily to remember I am sure if we were taught it in class it would take up the whole lesson.

Saw a video calculating rates of reaction on your channel. How can I use the rate of reaction to calculate the rate constant for a first-order reaction using the volume of gas collected?
