circle equation is:
\n" ); document.write( "\"%28x+-+a%29%5E2+%2B+%28y+-+b%29%5E2+=+r%5E2\"
\n" ); document.write( "where (a, b) is the center of the circle, and r is the radius\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, the circle equation with center of (5, -2) and diameter = 8 (radius = 8/2= 4) is:
\n" ); document.write( "\"%28x+-+5%29%5E2+%2B+%28y+-+%28-2%29%29%5E2+=+4%5E2\"
\n" ); document.write( "\"%28x+-+5%29%5E2+%2B+%28y+%2B+2%29%5E2+=+16\"
\n" ); document.write( "\"%28x+-+5%29%2A%28x+-+5%29+%2B+%28y+%2B+2%29%2A%28y+%2B+2%29+=+16\"
\n" ); document.write( "\"x%5E2+-+5x+-+5x+%2B+25+%2B+y%5E2+%2B+2y+%2B+2y+%2B+4+=+16\"
\n" ); document.write( "\"x%5E2+-+10x+%2B+25+%2B+y%5E2+%2B+4y+%2B+4+-+16+=+0\"
\n" ); document.write( "\"x%5E2+%2B+y%5E2+-+10x+%2B+4y+%2B+25+%2B+4+-+16+=+0\"
\n" ); document.write( "\"x%5E2+%2B+y%5E2+-+10x+%2B+4y+%2B+13+=+0\"
\n" ); document.write( "
\n" ); document.write( "
