Today we continued working with how the SAT covers circles. Last class I introduced to Andrew the equation of a circle. Today we practiced this concept further. I gave Andrew the equation of a circle and I asked Andrew to graph it. Andrew had to recall how to find the coordinates of the center of the circle. Then he had to take the square root of the number he saw to find the square root. Next I gave Andrew the graph of a circle and asked him to write the equation.
