Algebra.Com's Answer #139273 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! A circle witht the radius x-2 produces an area of 169pi cm^2 2. Find x. \n" ); document.write( "---------------------- \n" ); document.write( "r = x-2 cm \n" ); document.write( "-------------- \n" ); document.write( "Area = (pi)(x-2)^2 \n" ); document.write( "169pi = pi(x-2)^2 \n" ); document.write( "(x-2)^2 = 169 \n" ); document.write( "----------- \n" ); document.write( "x-2 = 13 or x-2 = -13 \n" ); document.write( "Positive solution: \n" ); document.write( "radius = 13 cm \n" ); document.write( "==================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
