A solid metal cylinder of radius 6 cm and height 18 cm is melted down and recast as a cone of radius 6 cm. What is the height of the cone?
\n" ); document.write( ":
\n" ); document.write( "Vol of cyl = \"pi%2Ar%5E2%2Ah\"
\n" ); document.write( "Vol of cone = \"%28pi%2Ar%5E2%2Ah%29%2F3\"
\n" ); document.write( ":
\n" ); document.write( "An easy way to do this:
\n" ); document.write( " Cone Vol = Cylinder Vol
\n" ); document.write( "\"%28pi%2A6%5E2%2Ah%29%2F3\" = \"pi%2A6%5E2%2A18\"
\n" ); document.write( ":
\n" ); document.write( "Divide both sides by \"pi%2A6%5E2\"; you have
\n" ); document.write( "\"h%2F3\" = 18
\n" ); document.write( ":
\n" ); document.write( "h = 18 * 3
\n" ); document.write( "h = 54 is height of the cone\r
