Algebra.Com's Answer #694576 by jorel1380(3719)![]() ![]() You can put this solution on YOUR website! For a cylinder, the formula for volume is v=πr²h, where r is the radius, and h is the height. So, for these rods, the measure is: \n" ); document.write( "V=π(3)²20=180π \n" ); document.write( "189 rods =189 x 180π=106877 cm³ of steel needed. ☺☺☺☺ \n" ); document.write( " |
