Hi there,
\n" ); document.write( "If it is a circular track
\n" ); document.write( "of 440 yards long.(Circumference)
\n" ); document.write( "Circumference = Pi x diameter
\n" ); document.write( "440 = Pi x 2r (Diameter = 2 x radius)
\n" ); document.write( "Radius = 440/2 x Pi
\n" ); document.write( "Area of circle = Pi x (440/2 x Pi)^2
\n" ); document.write( "Area of circle = 15406.i9 yds^2
\n" ); document.write( "= 15,400 yds^2 (nearest 100 yd^2)
\n" ); document.write( "Hope this helps :-)
\n" ); document.write( "
