8-24.

The given information involved diameters, not radii.

Refer to hint in part (a).

Each disk is a cylinder with a hole in the middle. How would you compute the volume of such a figure?

$V=\pi \left ( 10-\frac{i}{2} \right )^{2}(2)-\pi \left ( \frac{1}{2} \right )^{2}(2)$

Recall that the index will account for each and every weight. How many weights are there?
