You can put this solution on YOUR website!
If the arc length ( $\"S\"$ ) was the circumference ( $\"2%2Api%2AR\"$ ) of the circle, the area ( $\"A\"$ ) of the sector would be the entire area of the circle ( $\"pi%2AR%5E2\"$ ).
\n" ); document.write( "Set up a ratio.
\n" ); document.write( " $\"S%2F%282%2Api%2AR%29=A%2F%28pi%2AR%5E2%29\"$
\n" ); document.write( " $\"S%2F2=A%2FR\"$
\n" ); document.write( " $\"A=RS%2F2=%28%283.5%29%285%29%29%2F2\"$
\n" ); document.write( "where \n" ); document.write( "
