Algebra.Com's Answer #645981 by josgarithmetic(39618)![]() ![]() ![]() You can put this solution on YOUR website! The key to understanding the solution is recognize that a diagonal of the square is a diameter of the circle.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Letting d be diameter, \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Another key to solving is recognize the square is two 45-45-90 special right triangles, and you can use Pythagorean Theorem formula. \n" ); document.write( "Let x be a side of the square. \n" ); document.write( " \n" ); document.write( "and you can solve this for x.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "This solution almost but not finished, was done purely in symbols, and you can finish. \n" ); document.write( " |
