Diameter length of the given circle = 10 feet
\n" ); document.write( "And diameter of a circle = 2 times radius of the circle
\n" ); document.write( "Therefore 10 = 2r where r is the radius of the circle
\n" ); document.write( "That is 2r = 10
\n" ); document.write( "dividing by 2, we get
\n" ); document.write( "r = 5
\n" ); document.write( "Therefore the radius of the flower circle = 5 feet
\n" ); document.write( "Circumference of the circle by formula
\n" ); document.write( "= 2(pi)r
\n" ); document.write( "= 2X(22/7)X5
\n" ); document.write( "=220/7
\n" ); document.write( "=31.4285..
\n" ); document.write( "Therefore circumference of the circle is 31.43 feet approximately
\n" ); document.write( "
\n" ); document.write( "
