Algebra.Com's Answer #23694 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! If V = 121 = (pi)(r^2)h and we need to write h as a function of r, merely solve for h...thus \n" ); document.write( "121 = (pi)(r^2)h \n" ); document.write( "h = 121 / (pi)(r^2) \n" ); document.write( "If r = 3 cm, just plug it in and get \n" ); document.write( "h = 121 / 9(pi) \n" ); document.write( "I cannot graph it here due to the limitations of this interface, but you can start by plotting points, (r, h)...it will be hyperbolic in nature... \n" ); document.write( " |
