Algebra.Com's Answer #335194 by cleomenius(959) You can put this solution on YOUR website! First, we find the area \n" ); document.write( "Area = pi*r^2 \n" ); document.write( "5^2 = 25 * pi =78.54 \n" ); document.write( "Now, multiply this by the height. \n" ); document.write( "78.54*29 = 2277.66 \n" ); document.write( "================================================================== \n" ); document.write( "To determine where the decimal goes, determine what the place where the whole integers would be after the procedure. \n" ); document.write( "If doing by hand, it is best to line up your figures in a column. \n" ); document.write( "@|@|@|3|.|1|4 \n" ); document.write( "@|*|5|0|.| (this should be 25) \n" ); document.write( "@|@|2|9|.| \n" ); document.write( "---------- \n" ); document.write( "4|5|5|3|.| \n" ); document.write( "================================================================= \n" ); document.write( "One thing you did wrong was to use 50 instead of 25 in your calculations. \n" ); document.write( "3.14x50x29=4553. \n" ); document.write( "================================================================= \n" ); document.write( "Cleomenius. \n" ); document.write( " |
