SAT “Equation of a Circle” Practice Problems Worksheet Over the past few years, the College Board has transitioned from practically never asking about the equation for graphing a circle to now asking it on just about every test (I would say “every test,” but there is always that possibility it may not be on one test as a rare exception).

The equation of a circle is (x + 2) 2 + (y - 3) 2 = 9. Graph the circle. Problem 5 : A bank of lights is arranged over a stage. Each light illuminates a circular area on the stage. A coordinate plane is used to arrange the lights, using the corner of stage as the origin. The equation (x - 13) 2 + (y - 4) 2 = 16 represents one of the disks of ...
