Algebra.Com's Answer #208580 by Theo(13342) You can put this solution on YOUR website! The area of the pizza is 90 square centimeters.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The number of degrees in a circle is 360.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "360 / 40 = 9\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The pizza will deliver 9 slices if each slice creates an angle of 40 degrees at the center of the pizza.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Each slice is the same size, so the area of each slice has to be 90 / 9 = 10 square centimeters.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "That would be selection d.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
