SUMMARY
The discussion focuses on calculating the volume removed from a sphere of radius 2 when a cylindrical hole of radius \(\sqrt{3}\) is bored through its center. The volume of the removed section is determined using the integral \(4\pi\int\int x\sqrt{a^{2}-x^{2}}dx\), with limits of integration from \(\sqrt{3}\) to \(2\sqrt{3}\). Participants clarify that the volume of the cylinder should be subtracted from the total volume of the sphere to find the remaining volume. The correct limits for the integral are confirmed to be from \(\sqrt{3}\) to \(2\sqrt{3}\).
