PG problem file	Explanation
DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "PGML.pl" ); TEXT(beginproblem());	Initialization: This is built-in to MathObjects.
Context("Numeric")->flags->set(tolType=>'digits',tolDigits => 3, tolerateTruncation=>0);	Setup: The tolType=>'digits' switch to the digits tolerance. The tolDigits=>3 sets the number of digits to 3 (the default) The tolerateTruncation parameter is either 1 (true) or 0 (false).
BEGIN_PGML Graph the circle given by the following equation. [`[$circle_eq_lhs] = [$r ** 2]`] [_]{$gt} END_PGML	Main Text: This asks to graph the circle given by the equation. And the code: [_]{$gt} inserts the GraphTool.
BEGIN_PGML_SOLUTION The equation of the circle of the form: [`[$circle_eq_lhs] = [$r ** 2]`] has a center at [`([$h],[$k])`] and radius [$r]. To enter the graph, click the circle tool, then click the center at [`([$h],[$k])`] and then click a second point that is [$r] units from the center. This is easist going left, right, up or down from the center. END_PGML_SOLUTION ENDDOCUMENT();	This is the solution.
