document.write( ": I need help with this problem because I am totally lost. Here goes:Sally is making a cover for a round table. When finished, the cover will fit exactly with no excess hanging off. Sally has to cut the fabric circle with a founr inch larger diameter than the table to allow for hemming. If the table has a diameter of 72 inches, how much fabric does Sally need? (Use 3.14 for Pi. Round to two decimals places.) Thanks again for your help. Sharon \n" );

Hi Sharon,\r \n" ); document.write( "\n" ); document.write( "In order to complete her task Sally needs to cut a circle with a diameter of 72 inches + 4 inches for hemming or a total of 76 inches.\r \n" ); document.write( "\n" ); document.write( "1. We will be using the formula for the area of a circle (Pi r^2 = Area) \n" ); document.write( "Since r = the radius of the circle and the radius is equal to half of the diameter our value for r = 76/2 or 38 \r \n" ); document.write( "\n" ); document.write( "2. Pi r^2 = Area in square inches of fabric required for the job \n" ); document.write( "3. Pi(r)(r) = Area \n" ); document.write( "3. (3.14)(38)(38) = 4534.16 square inches (to two decimal places)\r \n" ); document.write( "\n" ); document.write( "Hope this helps! \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
