Solve the given problems by integration.An electric insulating ring for a machine part can be described as the volume generated by revolving the region bounded by $y=x^{2} \sqrt{x^{2}-4, y}=0,$ and $x=2.5 \mathrm{cm}$ about the $y$ -axis. Find the volume (in $\mathrm{cm}^{3}$ ) of material in the ring.

Sign Why square de y From the table of the integration, we get that integration off sign squares A X Maniacs is equal to X over two minus sign to a X over four a plus scene. If we make the same opposed, so is equal toe by while over two minus science. So why, over for from zero to fly over to She's going to They're fine by over four minus sign by over four minor 0/4 plus signed 0/40 is equal to buy squared over.
