A 25m long string cover the circular plate in form of a quadrant of a circle. find the area of the quadrant
\n" ); document.write( "----------------
\n" ); document.write( "If it covers it, you need to know the thickness of the string.
\n" ); document.write( "If it surrounds it, then:
\n" ); document.write( "r + r + 2*pi*r/4 = 25
\n" ); document.write( "r*(2 + pi/2) = 25
\n" ); document.write( "r = 50/(4 + pi)
\n" ); document.write( "-----------
\n" ); document.write( "\"Area+=+pi%2Ar%5E2%2F4\"
\n" ); document.write( "You can work that out.
\n" ); document.write( "
