Algebra.Com's Answer #604505 by mananth(16946)![]() ![]() You can put this solution on YOUR website! A cylindrical jar is 20 cm high with internal diameter 7 cm.\r \n" ); document.write( "\n" ); document.write( "find the volume of the cylinder / cm\r \n" ); document.write( "\n" ); document.write( "h=20, radius =3.5cm\r \n" ); document.write( "\n" ); document.write( "volume = pi*(3.5)^2*1\r \n" ); document.write( "\n" ); document.write( "= 22/7 *3.5*3.5*1\r \n" ); document.write( "\n" ); document.write( "=38.5 cm^3\r \n" ); document.write( "\n" ); document.write( "Change in volume of water is the volume of cube.\r \n" ); document.write( "\n" ); document.write( "volume of cube = 5^3 = 125 cm^3\r \n" ); document.write( "\n" ); document.write( "38.5 cm^3 = 1 cm height of jar \n" ); document.write( "125 cm^3 = ?\r \n" ); document.write( "\n" ); document.write( "125/38.5\r \n" ); document.write( "\n" ); document.write( "=3.25 cm\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " An iron cube of edge 5 cm is immersed completely in the water which was originally 12 cm high ,present in the jar.find the rise in the level of the water. \n" ); document.write( " |
