As you know the area of the circle given by the formula:\"A=%28pi%29r%5E2\", where r \r
\n" ); document.write( "\n" ); document.write( "is the radius of the circle.Substitute and get:\"254.34=3.14%2Ar%5E2\" =>\r
\n" ); document.write( "\n" ); document.write( "\"r=sqrt%28254.34%2F3.14%29\", and \"D=2r=2%2Asqrt%2881%29=2%2A9=18+cm+\", where D is the \r
\n" ); document.write( "\n" ); document.write( "diameter of the circle.
\n" ); document.write( "
