Today is pi day 3.14159265

PI day never ends.

you figure it for each circle.
but use X D then start at Pi R squared again and do X D again.
this gives you a volumetric measurement for each section.
if one circle is inside the other you have to subtract the difference.
or you have to do the math for a cone volume if they are continuously stacked to a point.

[birch]

What if the cones are continuously stacked but instead of a point, there is a slope? Should I be concerned with the slope intercept? I could quote some Shakespeare in response to the question, but I would hate to incorporate Literature into a day specifically dedicated to the science of mathematical expression.
