The smaller gear center is (7,0)
\n" ); document.write( "The larger gear radius is $\"R%5BL%5D=4\"$ .
\n" ); document.write( "The smaller gear radius is $\"R%5BS%5D=7-4=3\"$
\n" ); document.write( "The smaller gear equation is then
\n" ); document.write( " $\"%28x-7%29%5E2%2By%5E2=3%5E2\"$
\n" ); document.write( " $\"%28x-7%29%5E2%2By%5E2=9\"$
