is graphed in the standard (x, y) coordinate plane below. Suppose the circle rolls along the positive x–axis for 2 rotations and then stops. Which of the following is an equation of the circle in its new position?
Answer and Explanation
Your Answer is
Correct Answer is K
Explanation
The circle rolls twice, which is equivalent to moving two circumferences to the right. So the new center of the circle is (4 π,1), and the radius of the circle remains unchanged. Therefore K.
