You can put this solution on YOUR website!
First of all you need to find the formulas for the circumference \"%28C%2Fd%29=pi\" and the area of a circle is \"r%5E2%2Api\"
\n" ); document.write( "C=circumfence
\n" ); document.write( "d=diameter 17.2=(8.6*2)
\n" ); document.write( "r=radius (8.6)
\n" ); document.write( "pi=3.14\r
\n" ); document.write( "\n" ); document.write( "So plug in your numbers first the area\r
\n" ); document.write( "\n" ); document.write( "\"8.6%5E2%2Api\"=232.3521927\r
\n" ); document.write( "\n" ); document.write( "now the circumfrence\r
\n" ); document.write( "\n" ); document.write( "\"%28C%2F17.2%29=3.14\"
\n" ); document.write( "multiply 17.2 on both sides of the = sign
\n" ); document.write( "17.2*(C/17.2)=(3.14*17.2)
\n" ); document.write( "C=54.03539364
\n" ); document.write( "
\n" ); document.write( "
\n" );
