2*pi*r= 20*pi
\n" ); document.write( "r=10
\n" ); document.write( "the diagonal of the square will be twice the radius.
\n" ); document.write( "diagonal = 20
\n" ); document.write( "The diagonal is the hypotenuse of traiangle with the legs as the sides of the square
\n" ); document.write( "20^2=2x^2
\n" ); document.write( "400=2x^2
\n" ); document.write( "200=x^2
\n" ); document.write( "x= sqrt(200)\r
\n" ); document.write( "\n" ); document.write( "Area will be sqrt(200)*sqrt(200)
\n" ); document.write( "= 200 sq. cm
\n" ); document.write( "
