Two metallic disks having the thicknesses ¼ inch and 1/6 inch and the diameters of 5 inches and 3 inches, respectively, are melted and recast into a single disk having a diameter of 6 inches. Find its thickness. \n" ); document.write( "
Algebra.Com's Answer #252921 by mananth(16946) You can put this solution on YOUR website! 1/4 inch - 5 \" diameter = 2.5 inch radius. \n" ); document.write( "volume = pi*2.5*2.5*1/4 \n" ); document.write( "V= 4.91 cu.in \n" ); document.write( "1/6 inch -3 \"diamter = 1.5\" radius \n" ); document.write( "V= pi*1.5*1.5*1/6 \n" ); document.write( "= 1.18 cu.in \n" ); document.write( "Total = 4.91+1.18=6.09 \n" ); document.write( "... \n" ); document.write( "Volume = pi*3*3*h \n" ); document.write( "6.09/(pi*3*3)=h \n" ); document.write( "h= 0.215inch or 1/5\" \n" ); document.write( "... \n" ); document.write( "m.ananth@hotmail.ca \n" ); document.write( " |
