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.
