Question 101

The diagram shows a circle, with centre CCC, where C C\,C has coordinates (−3,−3)(-3,-3)(−3,−3). The circle intersects the xxx-axis at A A\,A and intersects the yyy-axis at BBB. The sector ABC ABC\,ABC is shown on the diagram.

The angle ACB ACB\,ACB is π6\displaystyle \frac{\pi}{6}6π​ radians and the perimeter of sector ABC ABC\,ABC is 12+π12+\pi12+π.
