Make a ratio.
\n" ); document.write( "The entire circle would have an area of $\"pi%2A%283%29%5E2=9%2Api\"$
\n" ); document.write( "The central angle then would be $\"2pi\"$ .
\n" ); document.write( " $\"%289pi%29%2F%282pi%29=A%2F%28%283%2F5%29pi%29\"$
\n" ); document.write( " $\"9%2F2=%285%2F3%29%28A%2Fpi%29\"$
