A cylinder has its height doubled and its radius cut to one-third.
\n" ); document.write( " What is the ratio of the volumes of the modified cylinder to the original cylinder?
\n" ); document.write( ":
\n" ); document.write( "Let original cylinder have a radius of 9, a height of 10
\n" ); document.write( ":
\n" ); document.write( " $\"old%2Fnew\"$ = $\"%28pi%2A9%5E2%2A10%29%2F%28pi%2A3%5E2%2A20%29\"$ = $\"2544.690049%2F565.4866776\"$ = 4.5 or a ratio of 9:2 \n" ); document.write( "
