Algebra.Com's Answer #140043 by feliz1965(151)![]() ![]() ![]() You can put this solution on YOUR website! We need to use the volume of a sphere formula.\r \n" ); document.write( "\n" ); document.write( "The formula is:\r \n" ); document.write( "\n" ); document.write( "V = 4/3 times pi times r^3\r \n" ); document.write( "\n" ); document.write( "You were given the dimater to be 9 meters.\r \n" ); document.write( "\n" ); document.write( "The radius = 1/2 of the given diameter.\r \n" ); document.write( "\n" ); document.write( "So, our radius is 4.5 meters. \r \n" ); document.write( "\n" ); document.write( "We now plug and chug.\r \n" ); document.write( "\n" ); document.write( "V = 4/3 times 3.14 times (4.5)^3\r \n" ); document.write( "\n" ); document.write( "V = 1.3 times 3.14 times 91.125\r \n" ); document.write( "\n" ); document.write( "Can you finish now?\r \n" ); document.write( "\n" ); document.write( "By the way, the choices given do not match the right answer for the volume of this sphere. Are you sure there is no typo here?\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
