Question 118

The diagram shows a circle, with centre CCC, with equation (x+2)2+(y+1)2=25(x + 2)^2 + (y + 1)^2 = 25(x+2)2+(y+1)2=25. 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.

A circle with centre C intersects the x-axis at A and the y-axis at B, with sector ABC shaded.

a.
