Algebra.Com's Answer #565759 by rothauserc(4718)![]() ![]() You can put this solution on YOUR website! A cone has volume V = 1/3 * pi * r^2 *h \n" ); document.write( "solve equation for h \n" ); document.write( "h = (3*V) / (pi * r^2)) \n" ); document.write( "h = (3*108*3.141592654) / (3.141592654 * 81) = 4 cm \n" ); document.write( " \n" ); document.write( " |
