If a round 8-inch diameter pizza serves two students, how many students should two 12-inch diameter pizzas serve? \r
\n" ); document.write( "\n" ); document.write( "a. 9 b. 8 c. 6 d. 4 e. NG\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since one 8-inch pizza serves 2 students, then this means that a pizza with an area of \"16pi\" serves 2 students \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "A pizza with a diameter of 12 inches has an area of \"36pi\". Therefore, 2 pizzas with diameters of 12 iches each both have a total area of \"72pi\" squared inches.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Using proportions, we can determine how many students two 12-inch diameter pizzas can feed. By making the amount of students equal to S, we get the following:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"2%2FS+=+16pi%2F72pi\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Cross-multiplying, we get: \"S16pi+=+144pi\" \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"S++=++144pi%2F%2816pi%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"S++=++9cross%28144pi%29%2Fcross%2816pi%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore, S, or the amount of students that two 12-inch diameter pizzas will serve is\"highlight_green%289%29\" \"highlight_green%28CHOICE_A%29\"
\n" ); document.write( "
\n" );
