If you triple all dimensions of a cone, will the surface area triple:
\n" ); document.write( ":
\n" ); document.write( "Let's see using the surface area equation:
\n" ); document.write( "\"%28pi%2A%283r%29%5E2%29%2B%28pi%2A%283r%29%2A%283L%29%29\"
\n" ); document.write( "---------------------- =
\n" ); document.write( "\"%28pi%2Ar%5E2%29%2B%28pi%2Ar%2AL%29\"
\n" ); document.write( ":
\n" ); document.write( "\"%28pi%2A9r%5E2%29%2B%28pi%2A9rL%29%29\"
\n" ); document.write( "---------------------- =
\n" ); document.write( "\"%28pi%2Ar%5E2%29%2B%28pi%2Ar%2AL%29\"
\n" ); document.write( ":
\n" ); document.write( "Factor out 9 in the denominator
\n" ); document.write( "9(\"%28pi%2Ar%5E2%29%2B%28pi%2Ar%2AL%29%29\")
\n" ); document.write( "---------------------- =
\n" ); document.write( "\"%28pi%2Ar%5E2%29%2B%28pi%2Ar%2AL%29\"\r
\n" ); document.write( "\n" ); document.write( "Cancel out the rest of it,
\n" ); document.write( "you end up with 9 times the surface area if you triple the dimensions
\n" ); document.write( "
\n" ); document.write( "
\n" );
