I didnt get how to write an equationin in this problem; Write an equation of a circle with center at the origin and radiu 6.
\n" ); document.write( "-----------------------------
\n" ); document.write( "If center is at (0,0) and radius is \"r\", the equation is
\n" ); document.write( "x^2 + y^2 = r^2
\n" ); document.write( "----------------------
\n" ); document.write( "Since r = 6 you get:
\n" ); document.write( "x^2 + y^2 = 36
\n" ); document.write( "=====================
