Hey :)\r
\n" ); document.write( "\n" ); document.write( "The volume of a cylinder is π r^2 h and you said that the radius = 5 cm and height = 4 cm\r
\n" ); document.write( "\n" ); document.write( "Using substitution:\r
\n" ); document.write( "\n" ); document.write( "Volume = πr^2 h
\n" ); document.write( " = 3.14 * 5 * 5 * 4
\n" ); document.write( " = 3.14 * 100
\n" ); document.write( " = 314 cm3\r
\n" ); document.write( "\n" ); document.write( "The volume of a cone is $\"%281%29%2F%283%29\"$ πr^2 h and you said that the radius = 3 cm and height = 8 cm\r
\n" ); document.write( "\n" ); document.write( "Using substitution:\r
\n" ); document.write( "\n" ); document.write( "Volume = $\"%281%29%2F%283%29\"$ πr^2 h
\n" ); document.write( " = $\"%281%29%2F%283%29\"$ * 3.14 * 3 * 3 * 8
\n" ); document.write( " = 3.14 * 3 * 8
\n" ); document.write( " = 3.14 * 24
\n" ); document.write( " = 75.36 cm^3(approx.)\r
\n" ); document.write( "\n" ); document.write( "Ratio of cylinder : cone
\n" ); document.write( " 314 : 75.36\r
\n" ); document.write( "\n" ); document.write( "I'd reduce it, but I don't want to take away from the credibility of the answer :) I hope this helps. Went over it quite a few times, but there may be a few mistakes. All the best :) x \n" ); document.write( "
