an circle is centered at the point (-3,2) and has a radius of length 7. what is the equation?
\n" ); document.write( ".
\n" ); document.write( "Since the standard circle equation is:
\n" ); document.write( "(x-h)^2 + (y-k)^2 = r^2
\n" ); document.write( "where
\n" ); document.write( "(h,k) is the center
\n" ); document.write( "r is the radius
\n" ); document.write( ".
\n" ); document.write( "mapping what was given we have:
\n" ); document.write( "(x-(-3))^2 + (y-2)^2 = 7^2
\n" ); document.write( "(x+3)^2 + (y-2)^2 = 7^2
\n" ); document.write( "(x+3)^2 + (y-2)^2 = 49
\n" ); document.write( " \n" ); document.write( "

\n" );
