Volume of a sphere by circle-areas

    Instead of the shell method, can't one find the volume of a sphere by integrating/summing its horizontal areas?

    Sure, if you mean using horizontal disks of thickness Δy. You can't sum areas to get a volume. You can sum increments of volume to get a total volume.
