Algebra.Com's Answer #539407 by harpazo(655)![]() ![]() You can put this solution on YOUR website! Use the formula for the volume of a cylinder.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Volume of a cylinder = ╥ r² h\r \n" ); document.write( "\n" ); document.write( "We need the radius which is 1/2 of the diameter.\r \n" ); document.write( "\n" ); document.write( "Well, what is 1/2 of 9? It is 4.5, right? That is our radius.\r \n" ); document.write( "\n" ); document.write( "V = ╥ (4.5cm)² (20cm)\r \n" ); document.write( "\n" ); document.write( "V = ╥ (20.25cm)(20cm)\r \n" ); document.write( "\n" ); document.write( "V = ╥ (405cm)^3\r \n" ); document.write( "\n" ); document.write( "Answer: V = 405╥(cm)^3\r \n" ); document.write( "\n" ); document.write( "Remember that volume is measured in cubic units. \n" ); document.write( " |
