Algebra.Com's Answer #614221 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! Use integration method to find the volume generated by two curves, \n" ); document.write( "-------------------- \n" ); document.write( " \n" ); document.write( "----------- \n" ); document.write( "You can see in the graph that the 2 curves are symmetrical about x = 1, and about the x-axis. \n" ); document.write( "---- \n" ); document.write( "--> find the volume of the left half rotated about the x-axis. \n" ); document.write( "----------- \n" ); document.write( " \n" ); document.write( "Using disks centered on the x-axis: \n" ); document.write( "Vol = pi*r^2*dx \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "--> Vol = 2pi per half \n" ); document.write( "Total volume = 4pi cubic units.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
