the rope is 10 m
\n" ); document.write( "tied at one end of a pole.
\n" ); document.write( "..
\n" ); document.write( "It can move in the field maximum from one side of the square to the other taking a circular path.
\n" ); document.write( "..
\n" ); document.write( "It can graze only an area of 1/4 of the area of a circle with radius 10m.\r
\n" ); document.write( "\n" ); document.write( "..
\n" ); document.write( "Area of circle with radius 10 = pi*10^2
\n" ); document.write( "Area = 314 sq. m
\n" ); document.write( "1/4 of 314 = 78.5 sq. m
\n" ); document.write( "
\n" );
