| Algebra.Com's Answer #201926 by oberobic(2304)      You can put this solution on YOUR website! volume of a cylinder = area of base * height = pi*r^2 * height \n" ); document.write( ". \n" ); document.write( "we are told volume = 91 and r=4 \n" ); document.write( ". \n" ); document.write( "91 = pi(4^2) * h \n" ); document.write( "91 = pi(16) * h \n" ); document.write( "91 = 16pi * h \n" ); document.write( ". \n" ); document.write( "dividing by 16*pi \n" ); document.write( ". \n" ); document.write( "91/(16*pi) = h \n" ); document.write( ". \n" ); document.write( "so the height is about 17.8678 in. \n" ); document.write( ". \n" ); document.write( "done \n" ); document.write( " |
