document.write( "I come up with, 12=6(1)^2/3 So the colume is 1.

Algebra.Com's Answer #89303 by oscargut(2103)![]() ![]() You can put this solution on YOUR website! No\r \n" ); document.write( "\n" ); document.write( "Because if the volume is 1 then r^3=1 and r=1 and surface=6 (not 12)\r \n" ); document.write( "\n" ); document.write( "so the solution is:\r \n" ); document.write( "\n" ); document.write( "12=6(r^3)^(2/3) then 2=r^2 then r=2^(1/2)\r \n" ); document.write( "\n" ); document.write( " then V=2^(3/2) \n" ); document.write( " |
