what is the equation for finding the diameter and radius of a circle when the area is given\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"Area%28A%29+of+a+circle+=+pi%2Ar%5E2\" so\r
\n" ); document.write( "\n" ); document.write( "\"A=pi%2Ar%5E2\" divide both sides by pi\r
\n" ); document.write( "\n" ); document.write( "\"A%2Fpi=r%5E2\" take square root of both sides\r
\n" ); document.write( "\n" ); document.write( "\"r=sqrt%28A%2Fpi%29\"---------------radius\r
\n" ); document.write( "\n" ); document.write( "\"r=d%2F2\" so
\n" ); document.write( "\"d%2F2=sqrt%28A%2Fpi%29\" multiply both sides by 2\r
\n" ); document.write( "\n" ); document.write( "\"d=2sqrt%28A%2Fpi%29\"---------------------diameter\r
